Connections between cortical (prefrontal cortex including infralimbic, prelimbic, and anterior cingulate cortices) and limbic (amygdala, hippocampus, and nucleus accumbens) regions. Within the amygdala, the CeA (brown) with its medial (left) and lateral (right) divisions, ITC (green), and LA/BLA are shown. Within the nucleus accumbens, the core (green) and shell (blue) divisions are shown. mPFC, medial prefrontal cortex; IL, infralimbic mPFC; PL, prelimbic mPFC; ACC, anterior cingulate cortex; NAc, nucleus accumbens.
