Septal nuclei

The septal nuclei are structures in the middle anteroventral cerebrum that are composed of medium-size neurons grouped into medial, lateral, and posterior groups. The septal nuclei receive reciprocal connections from the hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus.
