external definition

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 olfactory bulb, hippocampus, amygdala, hypothalamus, midbrain, habenula, cingulate gyrus, and thalamus. The septal nuclei play a role in reward and reinforcement along with the nucleus accumbens. In the 1950s, Olds & Milner showed that rats with electrodes implanted in this area will self-stimulate repeatedly in order to experience a euphoric feeling (i.e. press a bar to receive electrical current that will stimulate the neurons). [WP,unvetted][Wikipedia:Septal_nuclei].

Any of the groups of neural nuclei situated in the septal region which have afferent and cholinergic efferent connections with a variety of forebrain and brainstem areas including the hippocampus, the lateral hypothalamus, the tegmentum, and the amygdala.
