The septal nuclei (medial olfactory area) are a set of structures that lie below the rostrum of the corpus callosum anterior to the lamina terminalis (the layer of gray matter in the brain connecting the optic chiasma and the anterior commissure where the latter becomes continuous with the rostral lamina). The septal nuclei are composed of medium-size neurons which are classified into medial lateral and posterior groups.
