The '''septal nuclei''' are structures in the middle anteroventral [[Telencephalon|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]].
The septal nuclei play an important role in reward and reinforcement. In the 1950s, Olds & Milner showed that rats with electrodes implanted in this area will self-stimulate repeatedly (i.e. press a bar to receive electrical current that will stimulate the neurons) in order to experience a pleasurable feeling<ref>Positive reinforcement produced by electrical stimulation of septal area and other regions of rat brain.J Comp Physiol Psychol. 1954 Dec;47(6):419-27. </ref>.
