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.

In these instances, some form of input needs to be generated that replaces the signals that combine sensory perception with motor control and the brain needs to «learn» what these new signals mean.

Signals are sent to the motor control center in the brain cortex to say, «Yes, go ahead and do this,» or «No, stop.

These cells are responsible for sending signals out of the cerebellum, a region of the brain best known for its role in motor control and coordination.
