| Brain: Septal nuclei | ||

| Latin | nuclei septales | |

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)[1].
