...OVIDENCE, R.I. -- How information is stored in the nervous system, a key to memory and learning, is one of the hottest topics in neuroscience today. New research conducted at Brown University and Duke University Medical Center, published in the current issue of Science , fills in important details about cel......ity function that presumably describes bias in the nervous system for different movements.
