Extended amygdala

The extended amygdala is a macrostructure in the brain that is involved in reward cognition and defined by connectivity and neurochemical staining. It includes the central medial amygdala, sublenticular substantia innominata, the nucleus accumbens shell, and the bed nucleus of the stria terminalis. The boundaries are indistinct in Nissl stained sections.
