Hedonic hotspots and anatomical circuits that distinguish the nucleus accumbens hotspot in rostrodorsal medial shell as a unique site (anatomy based on Thompson and Swanson (TS symbol in orange boxes; 2010) and on Zahm and colleagues (Z symbol in purple hexagons; 2012). Thompson and Swanson [66] reported that the nucleus accumbens hotspot of rostrodorsal medial shell is uniquely embedded in its own closed-circuit corticolimbicpallidal-thalamocortical loop, connecting discrete input subregions and output subregions, and segregated from other parallel loops passing through other regions of medial shell. Zahm and colleagues suggested additional unique connections for the rostrodorsal hotspot [65]. GABAergic projections are indicated in red, hedonic hotspots are marked in yellow, glutamatergic projections are green, and dopaminergic projections are marked in blue.
