Location of recording arrays. Panels are coronal atlas sections (Paxinos and Watson, 1998) showing the approximate locations of recording arrays. Each gray box represents one array and was plotted on the atlas section nearest to the center of the array in the anteroposterior direction. The width of each box indicates the mediolateral extent over which the electrolytic lesions and/or electrode tracks were identifiable for each array. The height of each box indicates the dorsoventral distance over which the array was driven during the course of the experiment. Although some arrays are shown to project outside the NAc, we took care to ensure that only NAc neurons were included in the study.
