Classical studies have been focused on understanding the role of gustatory areas in evaluating the sensory component of taste. However, recent studies have suggested an involvement of gustatory areas, specifically the insular cortex, in guiding behavior on the basis of anticipation of food. At present, however, no causal link between gustatory cortex anticipatory activity and feeding behaviors has been demonstrated. The experiments in this study combine electrophysiological, pharmacological, and optogenetic approaches to establish, for the first time to our knowledge, that cue-evoked activity in the gustatory cortex is necessary to drive food-oriented behaviors. These results demonstrate that the integration between perception and action can occur also in primary sensory areas.
