Work in the Schieber lab by Marc Schieber and Kevin Mazurek was included in "The Sensory Revolution" in Psychology Today.
Our senses are under constant threat from the stimuli, routines, and ailments of the modern world. Fortunately, neuroscience is inspiring remedies that not only restore sensory input but radically alter it.
Sometimes sensation makes its way to the brain but doesn't alter behavior because the brain's wiring fails, as in stroke or localized brain damage. Neuroscientists Marc Schieber and Kevin Mazurek, both at the University of Rochester, have demonstrated a method that might bypass these downed lines. They've trained two monkeys to perform four instructed actions, such as turning a knob or pressing a button. But that instruction takes the form of an electrical signal sent to electrodes in the monkeys' premotor cortex, an area between the sensory cortices and the motor cortex, which controls muscle movement. Even without any sensory instruction, the monkeys were nearly 100 percent accurate at interpreting the signal and performing the correct action.
