Each time, they got a measurable
electrical signal; when metals such as platinum
replaced the semiconductor strip, the effect disappeared, they report in the 17 August online Physical Review Letters.
A new study authored by Marc Schieber, M.D., Ph.D., and Kevin Mazurek, Ph.D. with the University of Rochester Medical Center Department of Neurology and the Del Monte Institute for Neuroscience, which appears in the journal Neuron, shows that very low levels of
electrical stimulation delivered directly to an area of the brain responsible for motor function can instruct an appropriate response or action, essentially
replacing the
signals we would normally receive from the parts of the brain that process what we hear, see, and feel.
