FIGURE 1

Location of the subregions along the rostrocaudal axis of the insular cortex (IC). (Top) Photomicrograph of coronal brain sections depicting the microinjection sites of representative animals (left hemisphere) and diagrammatic representations modified from the rat brain atlas of Paxinos and Watson (1997) (right hemisphere) indicating the anterior [interaural (IA) 12.7 mm], rostral posterior (IA 9.7 mm), and caudal posterior (IA 7.6 mm) subregions of the IC. Arrows and red squares indicate the microinjection site and IC region. (Bottom) Representation of a sagittal section of the rat brain modified from the rat brain atlas of Paxinos and Watson (1997) indicating the position of the anterior (12.7 mm), rostral posterior (9.7 mm), and caudal posterior (7.6 mm) subregions of the IC along the rat brain. The numbers indicate the IA distance.
