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.
Researchers have given rats the ability to "touch" infrared light by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes tactile information. The study demonstrated that a novel sensory input could be processed by a cortical region specialized in another sense without "hijacking" the function of this brain area.
Researchers electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart - one in Durham, N.C., and one in Natal, Brazil.
Advances in robotics have made it possible to create artificial legs that can duplicate the natural movement of human legs. The research could help improve the mobility of lower-limb amputees.
Researchers restored behavior in a rat model of TBI using a neuroprosthetic device.
Researchers record the neural activity of monkeys as the plan to reach in order to design better neuroprosthetics.
A new method of treating phantom limb pain which utilizes several technologies is providing successful.
By electrically stimulating the severed part of the spinal cord, researchers were able to make a completely paralyzed rat walk over obstacles.
