The Physiological Mechanisms of Motivation

“…Not only are gustatory stimuli chemically specified in a behaviorally active form, but also the neuroanatomical basis for this afferent information has been defined, at least in the brain stem (Norgren, 1977). To a degree, the gustatory afferent system is separable from the bulk of the trigeminal system, which in conjunction with the olfactory system provides the intraoral sensory information that characterizes more complex foods.…”
