Figure 7.

Amygdalar signals reach pOFC directly and indirectly through the thalamus. Bottom, Neurons from the amygdala that project to the thalamus are large and express VGLUT2 (dark blue), whereas amygdalar neurons that project to pOFC are comparatively smaller and express VGLUT1 (light blue). Left, Excitatory CB neurons (light green) and excitatory PV neurons (dark green) in MDmc project to pOFC at a ratio of 2:1. Direct amygdalar projections target most densely the upper layers, whereas indirect projections through the thalamus may target upper and middle layers through CB and PV thalamic neurons to enhance cortical signaling of affective content.
