Brain regions analyzed.

<p>Coronal diagrams of rat brains show the areas in which gene expression was analyzed, black boxes to scale. (<b>A</b>) 0.5 mm² areas in prelimbic (<b>PRL</b>) cortex and orbitofrontal cortex (<b>OFC</b>). (<b>B</b>) 0.5 mm² areas in anterior cingulate cortex (<b>CG1</b>), dorsomedial striatum (<b>DMS</b>) and dorsolateral striatum (<b>DLS</b>), and 0.2 mm² areas in nucleus accumbens core (<b>NAc</b>) and shell (<b>NAs</b>). (<b>C</b>) 0.2 mm² areas in basolateral amygdala (<b>BLA</b>) and 0.3 mm² areas in the subregions (<b>CA1</b>, <b>CA3</b>) of the hippocampus.
