Figure 1

Bilateral representation of cannula sites aimed at the nucleus accumbens shell (NAcS) region of 56 rats using Figures 12, 13 and 14 of the stereotaxic atlas of Paxinos and Watson [22]. The bilateral cannulae were localized within the shell region of the NAcS, or bordered the core and shell regions of the NAc, or bordered the NAcS and immediately adjacent ventral diagonal band area. Multiple animals had highly similar cannula placements, and there was considerable overlap of placements for the animals receiving SCH23390 (SE, n=12) and raclopride (RE, n=12) in the Expression paradigm, and for the animals receiving SCH23390 (SA, n=7), raclopride (RA, n=6) and vehicle (Yoked Control, YA, n=19) in the Acquisition paradigm.
