Researchers have successfully induced the sensations of touch and movement in the arm of a paralyzed man, with the help of a tiny array of electrodes implanted into the somatosensory cortex.
University of Rochester researchers report low levels of electrical stimulation delivered to areas of the brain responsible for movement can instruct an appropriate response, replacing signals for sensory processing.
Using a brain computer interface, researchers help a paralyzed man regain a sensation of touch via a robotic arm.
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.
