Figure 3. MTEP infused into the dlSTR does not affect relapse or extinction learning in sucrose self-administering animals.

Figure 3

(A) Mean number pellets attained during sucrose self-administration. (B) Intra-dlSTR MTEP does not affect context-induced relapse following abstinence from sucrose self-administration. (C) Intra-dlSTR MTEP prior to the context-induced relapse test (extinction Day 1) has no effect on extinction learning in subsequent days. (D) Diagrams of the rat brain coronal sections, adapted from Paxinos and Watson (2007), show the distribution microinjection sites in the dlSTR. Numbers indicate distance from bregma in the anteroposterior plane. N = 11–12/group.
