Processing Biological Signals (Invasive)
In another knowledge base article I review some of the technologies used to interface with the brain (Stimulating The Brain Using Invasive Technologies). This article presents, irrelevant as the to the technologies used, some of our current capabilities that I’ve noticed have generally escaped the general public’s attention.
Some of these articles are merely interesting, while others provide a glimmer into the abuses that could be suffered if technologies are not mediated by a trust-able governing body. Think I’m exaggerating? Consider that scientists have been able to detect, extract, and decode a person’s ‘inner voice’ – which is the voice that most people use to think. What could happen if this technology became available, enabling anyone to hear your inner most private thoughts? Who could you trust to regulate such a technology to protect you?
Here is a list of just a few of the more interesting studies that have been performed:
Decoding Personal Thoughts / Dreams:
- Can someone ‘listen’ in to my thoughts? Yes! Scientists are working on a device that will speak the thoughts in your mind – without your saying them! Another article here.
- Brain to Computer Interface translates brain signals into words.
- Brain to Computer Interface reconstructs speech from brainwaves. And another approach here, using the human auditory cortex.
- Brain To Computer Interface decodes spoken phrases from phone representations in the brain.
- A mind-reaching machine that can translate thoughts into speech is coming closer to reality.
Life Enhancing / Physical Disability Correction:
- Scientists have made a bionic eye that interfaces directly with the brain.
- Scientists create a bionic eye prototype that stimulates the visual cortex to restore sight.
- Wiring a silicon chip embedded in the eye directly to the optic nerve to restore sight in an animal.
- Worlds first paralyzed person to be ‘reanimated’ using his body and without prosthetics.
- A wireless Brain to Computer Interface!
- Extremely low-frequency magnetic field may be useful in the neuropathic pain therapies.
- An implant that stimulates your vargus nerve, relieving arthritis pain.
- Bionic eye prototype stimulates visual cortex to restore sight. Another article here.
- A new University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain, but don’t penetrate it. A year later, they are using the technology to interpret speech.
