nulceus accumbens circuitry
a. The ventral tegmentum sends projections to the nucleus accumbens and (other) limbic areas such as the Amygdala and Hippocampus. This is collectively called the “mesolimbic dopamine pathway.”
b. The tegmentum also projects to the PFC (but, significantly, not other cortical areas). This is called the “mesocortical dopamine pathway.” I’ll be lumping the mesolimbic plus mesocortical pathways together as the “dopaminergic system,” ignoring their not always being activated simultaneously.
c. The accumbens projects to regions associated with movement.
d. Naturally, most areas getting projections from the tegmentum and/or accumbens project back to them. Most interesting will be the projections from the amygdala and PFC.
