title: Neurophysiology: sensing and categorizing.
abstract: Objects differ along many stimulus dimensions, but observers typically group them into fewer 'categories' according to their potential use or behavioral relevance. New experiments in awake, behaving monkeys open a window onto the process of stimulus categorization within the central nervous system.
