Fig. 5.

Schematic representation of probe placements in the nucleus accumbens core–shell border for all groups. Groups include: day 2 and day 1 ethanol self-administration and the corresponding sucrose groups. Numbers above slices denote the location in millimeter from bregma. This figure was based on the rat brain atlas of Paxinos et al. (1999). The light gray shading indicates the core. The dark gray shading indicates the core–shell border, and the white area of the accumbens indicates the shell subregion.
