Models of the human brain, patterned on engineering control theory, could assist researchers control neurological diseases, according researcher who is using mathematical models of neuron networks from which more complex brain models emerge.
Scientists used an electronic prosthetic system to tap into existing circuitry in the brain at the cellular level and record the firing patterns of multiple neurons in the prefrontal cortex, the part of the brain involved in decision-making. They then “played” that recording back to the same brain area to electrically stimulate decision-based neural activity. Not only did it restore function, in some cases, it also improved it.
Millions of people suffering from multiple sclerosis, Parkinson's, muscular dystrophy, spinal cord injuries or amputees could soon interact with their computers and surroundings using just their eyes, thanks to a new device that costs less than £40 (~$63).
Sandia National Laboratories researchers, using off-the-shelf equipment in a chemistry lab, have been working on ways to improve amputees’ control...
