Figure 1.

Histological verification of the cannula injector placements. Cannula placement was verified after each experiment with the infusion of methylene blue dye as shown in the lateral (b) and medial (c) septum. Scale bars, 500 μm. a is an illustration of the septum showing successful cannula placements in the intermediate lateral septum (filled circles) and placements excluded from data analyses (open circles). d illustrates the central amygdala region targeted for antalarmin infusion, with an example section shown in e. LS, Lateral septum; MS, medial septum; LV, lateral ventricle; cc, corpus callosum; aca, anterior commissure, IC internal capsule; OP, optic tract; CEA, central nucleus of the amygdala; BLA, basolateral amygdala.
