This is the second page in the series – if you did not read the introductory page, “Physiology, Neuroscience, Quantum Biology, And The Bio-field” then I recommend you read it first, or you may become a bit lost in this information. I have highlighted text synchronous with my desire to remotely extract biological signals.


Glassbrain Project

In the public eye the brain is still not very well understood, and through my research I’ve noticed that government and private funded research is far more advanced than the general public is aware. There are a lot of patents held by a lot of larger companies – everything from improving vision to assessing mental states. The body generates electrical signals, and uses them as a basis for ‘inner-body’ communications (a way for organs to communicate with the brain). If you had a lot of time, I’d suggest you read “The Body Electric” by Robert Becker and Gary Selden. The book outlines how cells, the nervous system, and the brain work electrically.

Perhaps over-simplifying the above mentioned book, I’ll suggest that the body is like a large electrical circuit board, using the nervous system as a conduit for the organs, brain, and etc., to communicate with one another via electrical signals. As an example, here is how the body converts a mechanical input (sound pressure) into what we understand to be ‘sound’. Sounds enter the ear as sound waves (pressure), creating vibrations on our eardrum, which are converted into electrical signals that travel up the auditory nerve to the brain’s auditory cortex, which are then interpreted into something we recognize and understand as ‘sound’.

What Does The Nervous System Do And How Does It Work?

The nervous system interconnects the brain and organs in the body and allows them to communicate with one another. In a very basic sense, the nervous system is the “wires” that transmit electrical signals throughout the body. All of our senses are relayed through the nervous system. For instance, the sensations of ‘touch’ and ‘pain‘ are relayed for interpretation by the brain. If we touch something cold with our finger, then the nervous system would ‘conduct’ the appropriate signals to the brain, which would interpret it as having touched something cold – which after further processing might drive some sort of response. Although there are many different nerves in the body, sometimes a single nerve will connect up many different organs together.  To ensure the brain ‘knows’ which organ sent the signal, each organ in the body operates at a different frequency. Here is a great article describing how the electrical impulses are generated and how the nervous system ‘conducts’ these signals.

The nervous system also acts like a ‘translator’. It was once thought that the brain controlled every single motion and movement made in the body – however there are cells in the spinal column that translate messages between the brain and the motor neurons (which directly control muscles).  This collection of cells is called the locomotor central pattern generator (CPG). Without the CPG the brain would need to perform a lot of processing when you walked down the street – controlling each muscle movement while alternating each step and balancing (arm swinging, etc.). But these operations are instead ‘learned’ by the CPG, so all the brain needs to do is send the CPG a signal that it should walk (or run, etc.) and the CPG will perform all of the necessary learned actions – which raises the brains efficiency.

But this idea is not restricted to the CPG, it seems that the heart also has a grouping of neurons. In addition to sending messages to the brain using the nervous system, these approximately 40,000 neurons can also sense, feel, learn and even remember! Here is an article that shows how each of our hearts has its own little ‘brain’. As the heart can detect and react to emotional stress, feelings of happiness, and other emotions, we are therefore able to detect a person’s emotional state simply by reading the electrical signals generated by the heart. The heart is also a major contributor to the human biofield, generating electromagnetic signals significantly stronger than those of the brain!

It is interesting to note that some metabolic processes are controlled by the nervous system. A bit more detail about the design and functioning of the nervous system can be found here. And here is a slide show created by WebMD, describing how the nervous system works in more detail.

What Does The Brain Do?

We all know that the brain allows us to think, learn, navigate, rationalize, fantasize, dream, feel emotions, quantify fear, etc. etc.. Perhaps the core functioning of the brain could be summed up with the statement, “it processes any signals it receives and determines a response”. While most people know that the brain is the command center for the human nervous system, and that it regulates your bodily functions, most will not know that the brain is directly connected to the immune system (another article here, and here). Here is an article describing how scientists were able to ‘listen in’ to how the brain communicates with the immune system. Of course, therefore our overall health would have a direct effect on our brain – here is a study where they found that physically fit kids have bigger hippocampus than those less active. So I’ll suggest that you take care of your physical health – and stay fit!

For those interested, here are some more recent detailed mappings of the brain. And below are some good articles that I suggest you review:

  • A good and very simple overview of how the brain works can be found here. Albeit for teens, it’s full of good information – some of which I was unaware of!
  • A web page describing how the brain functions that was written by the US National Institute of Neurological Disorders and Stroke.
  • This “cute” video by Alistair Jennings provides an extremely basic overview of how the brain works.
  • The History Channel has a pretty good video describing the basic functionality of the brain and how it evolved.
  • A slide show, provided by WebMD, clarifying what the different parts of the brain do, how the nervous system functions, and how the two are interconnected.
  • And lastly, a fun way to visualize electrical brain activity can be found at the Glass Brain project, where you can visualize the electrical activity of the brain! Here is some more information.
  • As a point of interest, scientists have begun to research and explain what the feeling of Deja-Vu is, and how it is manifested in the brain.
What Are Neurons, Synapses, Nerual Networks, and Bio-Photons?
Neurons, Synapses, and Neural Networks

The brain uses electrically excitable cells called “neurons” that process and transmit information through electrical and chemical signals.  There are several types of specialized neurons:

  • sensory neurons respond to stimuli such as touch, sound, or light
  • motor neurons receive signals from the brain and spinal cord to cause muscle contractions and affect glandular outputs
  • inter-neurons which connect neurons to others within the same region of the brain or spinal cord

“Synapses” connect neurons together and conduct the signals that are generated. Neurons connect together to from “Neural Networks”. Here is an interesting article helping us to understand how the neurons in our brains are interconnected – shedding light into just how interconnected the information that is stored in the brain is. Here is an article detailing what neurons are and how they work.

Neurons can learn temporal patterns – for example when a signal (pulse – brief pause – pulse – long pause – pulse) was provided to neurons found in the cerebellum (an area in the brain that controls bodily movements, position, and balance), it was responded to with “response – brief pause – response – long pause – response”.  This means that the brain is capable of learning in different ways than we prior thought possible! As a side note I wonder how this additional input would have influenced the brain?


In recent years, a growing body of evidence shows that photons play an important role in the basic functioning of cells.  It turns out that many cells emit light as they work, and use this to communicate.  Here is an article that supports the idea that neurons in our brains are capable of producing photons (bio-photons). It is believed that photons are conducted through microtubles, which are the internal scaffolding inside the cells that provide structural support and allow the movement of cellular material. Bio-photons appear within the visible spectrum, from near-infrared through violet. Bio-photons are created during the electrical activity of the brain, and it is now believed that they are used to help co-ordinate activities in different parts of the brain (another article here).

Low Level Thought Processing

How Does The Brain Work?
Introduction – Interconnection With The Nervous System, Sensory Processing, and Low-level Thought Processing

Here is an interesting video showing how you can use fMRI to see brain activity (thoughts, emotions, pain) as it occurs.  A team of researchers used fMRI to follow a thought through the brain. While these articles are cool, describing how the brain actually processes thoughts is incredibly complicated, so I’m going to ease you into this.

It was mentioned above that the brain has different regions (sections) performing different functions, and that the nervous system connects each organ to the brain. To ensure that each section of the brain can discern their specific “inputs”, each section of the brain performs specific operations and operates at different frequencies, and are also partially electrically isolated from the other sections of the brain. This allows signals to be processed in the “correct” area of the brain without “interfering” with other areas while still allowing overall “information flow” throughout the brain. Most of the organs are connected to different spots on the brain, and at each of those connection points that section of the brain “processes” the received information and “produces” a result, with this result then being sent to other areas of the brain for further processing. This process continues through the hierarchy of the brain until it reaches the thalamus.

Introduction – Higher-level Thought Processing And Output / Response

The thalamus is located in the middle and on both sides of the brain and acts as a relay station between the different parts of the brain, processing sensory inputs (such as vision, touch, and hearing), and is also involved in directing the focus of our attention (screening out distracting stimuli).  Eventually, all processing is passed over to the cerebral cortex, which is connected to the spinal cord – so that they body can produce a reaction to all of the stimulus (inputs). Most people become conscious of their thoughts at the same ‘point’ in the brain (more detail to follow). It is interesting to note that the brain considers a number of inputs when making a decision, even those that we are not consciously aware of! For instance the act of hearing is a combined effort that includes the ears, the eyes, and the skin! (second article here). On a bit of a side note – it is interesting that people interpret the act of thinking as listening to their ‘inner-voice’ or via imagery.

And while most areas of the brain are focused on processing specific information, some parts of the brain can do two things at once – for example an area of the brain called, “Broca’s area”, can process language and music at the same time (which if you think about it makes sense because WE have defined the difference between musical sounds and the sounds of speech – there wouldn’t be a ‘difference’ if we spoke using musical sounds). Some sections of the brain work together to process thoughts (second article here).

Introduction – Information Flow Through The Brain

So, a logical question to ask is how do the different brain sections connect with each other / work with each other?  How do basic nervous system ‘inputs’ become conscious thought? The answer is that each of the main sections of the brain communicate with the other sections in such a way that could be compared to that of a computer network, with the brain having a small number of “control nodes” that communicate with each other. This can all be combined to describe the most current theory of how overall thought processing occurs in the brain. Essentially, the brain processes information in a hierarchical fashion, meaning that sensory information is processed by a part of the brain with the result being passed to a “node” which is then processed by another part of the brain – with this process continuing throughout the nodes in the brain until it reaches the section(s) where it can be consciously perceived by the person. It is at this time that a “final conscious decision” is made and the responses can be generated. Note that these brain nodes communicate information in a pattern which is common to each of us (hence why they are called, “common codes”).

In order to process the information received from the various organs in the body the brain uses several frequency bands to regulate the flow of information between “lower” and “higher” areas in the brain.  Therefore, information is processed from either the “bottom-up” or the “top-down”.  A working example: in the visual system information enters through the eyes and flows from lower to higher visual processing areas in the brain (i.e. “bottom-up”).  In other words, sensory input is continuously processed by the brain using the bottom-up principle as soon as a person observes something. Here is an article that describes how the act of thinking causes different frequencies to arise in the brain, which could help the brain to focus on only those memories and capabilities that are relevant to current activity or thought processing. Here is a chart outlining some research of the frequencies generated by the brain as it enters into different states. Here is another supporting article that advises how mice brains ‘shifted frequencies’ from 35Hz to 60Hz when they switched between their ‘left and right’ turn memory or referening landmarks while navigating a maze.

Scientists reviewed the most basic electrical parts of the brain: how they are physically interconnected and where they are physically located, and then used algebraic mathematics to determine how these elements could work together to further “process” information (The Cell).  The results seemed to point to the brain being capable of creating structures up to eleven dimensions! The paper is complicated, but does I’d like to review one very important abstract it presents – how do you retain memories; for instance if I asked you to think about the last time you were at a campfire, I’m sure you’d instantly think about how you felt overall. Then as you continued to think about it you would recall individual things, such as how big the fire was, how hot it was, how the flame looked in comparison to the sky / pond / lake, the people you were with, etc.. And if I asked you to, then I’m sure you could break each of those things down into other memories – like who each person is, where they live, etc., etc.. This is kind of like the ‘dimensions’ mentioned in the above paper.

“Big Data” has enabled a University of Massachusetts Amherst professor, Hava Siegelmann, to use fMRI data from tens of thousands of patients to better understand how thought arises from brain structure.

How Does The Brain Prioritize Thoughts?

Continuing with the above, the brain determines that one piece of information is more important than another using the “top-down” principle, and it uses previous experiences to organize information in the present context and to make predictions.  The “top-down” flow therefore influences the “bottom-up” flow and steers our attention towards things that are important in the current situation.  This can happen automatically, for example due to the sudden appearance of a threatening stimulus, as well as through attention (ex. when we are looking for something or following instructions).  Considering the volume of information being processed by the brain at any given moment, it is a way for the brain to bring your focus to the most important thing at any given moment.

It is thought that alpha waves enable different brain regions to ‘listen in’ on ‘like’ information. This makes sense, as there would be a need for a hierarchical, low-powered electrical system to efficiently and effectively communicate information across biological material. Here is another article that suggests that information seems to be communicated throughout the brain via a low intensity electrical field traveling at 0.1 meter per second! Here is another supporting article (on Note that there are other electrical fields generated by the brain, and scientists continue to discern what information each field carries. Having said all this, I wonder if all brain functions could be described by quantum sciences, and if these generated frequencies are merely the result of the brains overall electrical activity?

What Are The Principles Behind The Brain’s Functioning And How Does It Make Complex Decisions?

Here are some interesting articles that help you understand how the brain performs these functions:

How Does Memory Work?

Memory plays an important role in our every day life, sometimes in ways that we may not be consciously aware of, such as performing the awake mental replay of past experiences, which is critical for learning and making informed choices. While we have known for years that information is stored in two main memory areas in the brain (the hippocampus [short term memory] and the neocortex [long term memory]), we only recently learned the technique the brain uses to preserve its memories – how the brain codes episodic memory. And how the brain reconstructs prior events. And how the brain transfers our daily experiences into memory or discards them while we sleep (this includes subconscious subliminal messages). Scientists have also discovered the circuit that is dedicated to memory retrieval.

One of the more interesting recent discovery is one that contradicts the general understanding that the area the brain stores memory is a rigid structure. This new study shows that the brain has a ‘critical plasticity’ in its neuronal networks that ensures easier integration of new information. This plasticity allows neuronal networks to more easily incorporate new learning and eliminates the need to form new links to separate neurons every time something is stored in the brain. As well, once a memory is no longer needed, neurons can be more easily reassigned to other important tasks. The authors state, “We believe this trade-off ensures the delicate balance between the ability to incorporate new information while preserving old memories”.

Just how much memory do we have? Well, it is estimated that the brain can hold about a petabyte of data!

Mapping the Brain

I found a Ted Talks video where Allan Jones describes how the brain works by describing it as a giant map, and shows us how the electrical activity “adds up”. Different sections of the brain perform specific operations, and as our technologies allow for more detail in our studies, we are fine-tuning our understanding of the functions of these various brain regions.  As an example, our understanding of language comprehension was based on a 140 year old study performed on individuals having had a stroke (the studies focused on Wernicke’s region in the brain).  A more recent study identified that word comprehension is located in a region of the brain located more forward than Wernicke’s region, and that sentence comprehension is widely distributed throughout the language network.  Thus, a new atlas is being generated to help describe how these various areas of the brain work together.  Researchers running a project called, “Human Connectrome Project”, were able to create an updated brain map that is based on the brain activity of over 200 participants.  Published article here.  Cool video here.  More information can be found in this National Geographic Live video called, “Mapping the Brain“.

Researchers have also been able to read postmortem brain slices to determine how a rat had been trained to behave in response to specific sounds! Their work provides one of the first examples of how specific changes in the activity of individual neurons encode particular acts of learning and memory in the brain.

Decoding the Brain

Scientists have begun to reverse engineer the brain, and are also working to discover the mathematics used by the body in the generation and processing of biological signals. Here are some rather interesting articles:

High Level Thought Processing

Does The Brain Use ‘Common’ Circuits To Perform Tasks?

It makes sense that the brain would, in an attempt to be as efficient as possible, use ‘common circuits’ while processing thoughts. For example, when you read silently the part of your auditory cortex that usually responds to speech is also used to process written words as if they were spoken (your inner voice) [another article here]. I remain curious as to what other brain ‘circuits’ function in the same way.

How Does All This Come Together To Describe How The Brain Works (More Advanced)?

Building on all the above, basically our brains are an intricate network of neurons and synapses transmitting electrical signals that become memories, commands, and ideas. And when these neurons transmit data back and forth, they in turn create brain waves, or synchronous oscillations that aggregate and transfer information across different segments of the brain.

Every brain shares a common architecture that enables us to store and process raw information from our senses through to some sort of completion – such as the interpretation of a complex visual image, a reaction, or memory storage, etc. In every brain: information is stored in the same location, is processed in the same locations, and the ‘results’ are made available to the same locations in the brain for actioning.

The brain processes information in a hierarchical fashion, meaning that sensory information is processed by one part of the brain with the result then passed to a “node” which is then processed by another part of the brain – with this process continuing throughout the nodes in the brain until it reaches the section(s) where it can be consciously perceived by the person. It is at this time that a “final conscious decision” is made and the responses can be generated. Note that these brain nodes communicate information in a pattern which is common to each of us (hence why they are called, “common codes”). Here is an article that shows how a team worked to decode how the brain “pieces” the information that it stores together.

This implies that the information processed by the brain changes in type and complexity, becoming more specific along the way. For example, we know that words and images trigger specific neural reactions. The word ‘cat’ when heard is translated by the ear from mechanical vibrations into electrical signals, which then triggers the parts of the brain responsible for the concept of a ‘cat’, which would then be presented to a different part of the brain for processing. While there may be millions of neurons required to interpret the signals from the eyes as being that of a ‘cat’, and the ears to interpret the ‘meow’ sound, and the nose recognizing the cat odor, as the brain processes this information through the nodes it is eventually reduced to just three items – the cat is visible, has meowed, and the familiar odor is present.

Therefore, our life experiences (the environment that we are subjected to) is superimposed onto this common architecture for processing by the brain. What makes us each unique is our finite biological makeup (the subtleties of the development of our brain), our body chemistry, and our life experiences.

Therefore, if you could detect (read) the biological signals present at these different nodes in the brain hierarchy, then you would be able to decode the information being processed at the different levels of the brain – from the most basic (sensory) to the more complex (conscious thought).

Your brain processes most sensory information prior to your having become aware of it. Take for instance your eyes – your brain processes the information from your eyes (sensory), but you are not aware of this immediately – you only become aware once the signals have reached the part of your brain that you are conscious of and have filtered out the “noise”. In one experiment it was found that a computer reading biologically generated signals could detect that person’s decision prior to the person being aware that they had even reached a decision! Here is a humerus example, provided by Moran Cerf during a Ted Talk. It would be therefore possible for us to extract biologically generated signals, have them analyzed by computers, and have the results prior to our even being aware of any decisions having been made. This idea can also be connected with memory, where it has been found possible to create memories without having actually experienced anything related with them – just like in the “Matrix” movies!

Do We All Think Alike? Are Our Brain Patterns Essentially The Same?

Yes! Scientists have been able to find generalized patterns that exist in every person’s brain which can be used to identify what a person is thinking about with 100% accuracy! (Here is another article) This means that we no longer have to train computers to detect each person’s specific thought patterns in order to detect the thought!! What does that mean? It means that if I ask you to think about a light-bulb, house, or hammer, then your brain will (with minor deviance) use the same patterns as mine will, or anybody else’s, in creating that thought. This means that once the pattern is discovered and recorded for just one person, then that same pattern can be applied to everyone else.

With everyone’s brain having the same essential physical shape, and electrical design, and functional break-out, one could think it should be quite possible to extract higher-level thoughts using the same methodology. This would mean that you could extract high-level thoughts from a person, merely be recording and looking for common patterns behind the electrical signals that are generated by the thought process. And, this would imply that you could extract and decode complex thoughts using a significantly less bandwidth than prior anticipated.

Are Brain Waves, Heart Beat Patterns, and Other Bodily Functions Unique?

YES! No two people are exactly alike. Even twins will have different distinct cognitive functionality due to the random nature of cellular growth / death, and especially per their unique life experiences.

It is not even a question nowadays that everyone’s heartbeat and brain waves are unique (more articles here, here, here, here, here, and here).  Binghamton researchers have developed an EEG “brain-print” system that can identify people with 100 per cent accuracy, according to a recent study.  In this study, the team determined that the electrical structure of the brain is what makes each brain unique. And here is another article from another research team – and a team in Greece, who also investigated this concept. Berkeley, a university in the USA, has also performed research on this and developed a one-step, three-factor authentication method using ear-buds that could be used in consumer devices.

Want to isolate one individual out from the rest using stronger electrical signals generated by the body? Then I suggest reading the signals generated by the body’s muscles and using something like a person’s eye blink. An individual’s eye-blink is unique enough to identify that person from others in a crowd! Or use a system like the US Military is creating, where they are combining thermal imaging and facial-recognition technology to allow soldiers to better identify persons of interest in the dark. Of course, this implies a unique thermal footprint for individuals as well!

Brain Synchronicity

There is an interesting twist to this: even though everyone has uniqueness, consiering that our brain patterns are essentially the same, it seems plausable that our brains might be prone to synchronization. This literally means that brains will become synchronized with one another when performing complex tasks. For instance, a study revealed that monkeys’ brains synchronized as they collaborated to perform a motor task and that the level of synchronicity is influenced by proximity and social status.

Are Some Brains Are Better Than Others?

Though we are all taught that we are all the same and equals – science has proven that we are not!  Depending on how your brain is wired, you may be better at some tasks than other people. Researchers at Yale University in the US have found that images of brain activity taken by functional magnetic resonance imaging (fMRI) can be correlated to your level of intelligence.  While fMRI data doesn’t simply indicate how smart you are, connectivity patterns in brain activity do correlate to how well people perform in an intelligence test, according to the researchers.  “The uniqueness seems to be tied to cognitive function in some way,” said Poldrack, with stronger connections in participants’ prefrontal and parietal lobes correlating to better intelligence test scores.

The Brain Generates Electrical Energy, Which Can Be Translated To Magnetic Fields – What Does That Look Like?

Great question! One of the reasons I’ve worked to briefly educate individuals on how the nervous system and brain function both biologically and during thought is to help the reader have a better understanding of how biological signals are created by the body, and how they are formed / shaped within the body’s structure. I was happy to find some information on this on the Human Connectome Project website. Perhaps also recognizing that people do not like to read dry papers, they’ve added a fair bit of color to the presented information and enable individuals to ‘fly through’ the electrical signals / magnetic fields that are generated by the brain.

But wait! If the brain generates electrical energy, and electrical energy can be directly translated to magnetic fields, then does that mean that there is a connection between electrical and magnetic energy?

Yes! Here is a book, where in Chapter 9 it is identified that high frequency electromagnetic fields which were amplitude modulated at a range of low frequencies of approximately 15 Hz, induced calcium efflux from chick brains. This frequency range was dubbed a frequency “window”. The test results indicated that certain combinations of frequency and magnetic field strength had positive results – which implies that the ratio of frequency to magnetic field strength is biologically important. This is all referred to as the “Ion Cyclotron Resonance Hypothesis” (ICR). What makes this possible? The physiological activity of cell signalling ions could be influenced when the ratio of applied frequency to the static magnetic field is equal to the ionic charge-to-mass ratio. It is interesting to note that if we consider the Earth’s magnetic field strength (approx 50μT) we calculate that the cyclotronic frequencies for ions involved in many biologically important ions (used for cell signaling) are in the ELF range: Mg2+ (63.2 Hz), Ca2+ (38.3 Hz), Zn2+ (23.5 Hz), and K+(19.7 Hz).


Research into what makes us ‘conscious’ continues to be on-going, but a team of scientists discovered that consciousness seems to be controlled by three neurons.  During a woman’s treatment for epilepsy, electrodes were placed near a brain region called the “claustrum” and noticed when they were stimulated she stopped reading and stared blankly into space.  She didn’t respond to voice or gestures, and her breathing slowed.  When the stimulation was stopped, she regained consciousness and had no memory of the lost period.

Studies on mice have found that there are three giant neurons emanating from the claustrum, which connect to many regions in both hemispheres of the brain.  One of those neurons wraps around the entire brain like a ‘crown of thorns’.  It is believed that the giant neuron may be coordinating signals from different brain regions to create consciousness [Sources: Nature, Quartz, New Scientist]. There is also the possibility that Quantum Biology can assist us in our understanding of how the brain generates consciousness.

Is It Possible To Isolate One Person’s Biological Signals Out From The Rest?

Yes! Our bodies are all essentially the same, having the same basic shape, limb count and placement, and with our nervous systems coursing throughout the body in common routes and connecting up to the brain at common locations. That we all share the same fundamental commonalities between our bodies and brains is not a new idea – take for example that we all share the same benefits of taking medications – or that psychotropic drugs usually affect our moods in the same way! As well, you can adjust anyone’s morality by placing a specifically-tuned pulsed magnet on a certain spot on their head! While we will have differing levels of effectiveness or may have side-effects, only a minority will not see the same intended benefits. This starts to make it look impossible….

So then what makes each person unique? Well, first no two people are exactly the same (cell count, body shape, size, etc.). Plus everyone’s biologically generated signals and frequency will be slightly different due to their biological make-up, body / brain / internal organ shapes, and their perception of life events. For instance, testing has shown that every person generates unique brain and heart signatures. It has even been found that your genes also play a part in making your brain wave patterns unique. And, everyone’s vocal system is unique. Therefore, all of the biological signals generated by the body will also be unique. Also helping is that we are able to determine a person’s sex purely using brain scans!

We are already able to, using electronics, filter out one specific signal from others that are received by an antenna – just like your car radio or TV! Of course we are able to do much more if we add digital systems to the mix! It would actually be VERY EASY to isolate one person out from the many – the hard part right now is – how can we remotely extract biological signals?

I now suggest you read the next section, “Effects Of RF On The Body“.
