Mind Eraser. No Chaser
From 1935 – 1982 one of the USA’s largest chemical companies actually had a slogan “Better living through Chemistry.” Today science should adopt the six million dollar man theme “we can make you stronger than you were before, faster and now have better recall.”
Scientist's at Wake Forest and University of Southern California published their findings Friday on a neuro-prosthetic device that appears to enhance recall abilities in the rats they implanted the device into.
This milestone set the stage for the possibility of repairing damaged neurons caused by strokes, traumatic brain injuries and a host of other debilitating cognitive disorders in humans.
Daryl Kipke Professor of Bioengineering at the University of Michigan said, “We are just scratching the surface when it comes to interacting with the brain, but this experiment shows what's possible and the great potential of interacting with the brain in this way.” Presently neuro- scientists are using this type of implant in patients with prosthetic limbs so movement can be controlled by thought.
Mimicking the firing patterns of neurons implants has already aligned human thoughts to computer cursors for communications as well as movement of external devices. Internalizing the implants function to supplement cognitive deficits seems the next logical step.

Sam A. Deadwyler and his team of Wake Forest Scientists implanted tiny electrodes into two neighboring areas of the hippo-campus in the rats brains. Humans and rats form and store new memories in these areas called CA 1 and CA 3. The attached electrodes record activity and communication between these specific areas of the brain to a computer. To test the efficacy of the implant the rats were trained to push a lever for water, they had to remember which lever to push in order to receive their reward. After training researchers then injected the rats with a chemical that shuts down CA 1 and the rats didn't seem to remember which lever to push. When the scientists replayed the recorded CA 1 signal from the computer back to the implant the rats miraculously remembered their training and pushed the correct lever.
