It consists of the Kölliker-Fuse nucleus and the medial parabrachial nucleus.
In non human primates, the medial nucleus (often named dorsomedian) is subdivided into several subnuclei.
The strong interrelation between the medial nucleus and the frontal cortex is known for long.
Anteriorly there is only an incomplete boundary with the medial nucleus.
A major projection from the medial septal nucleus terminates in the hippocampal formation.
This makes sense, as this is the area which receives direct input from the medial geniculate nucleus of the thalamus.
The medial geniculate nucleus is part of the thalamic relay system.
One spot that is particularly rich in receptors is known as the ventral medial nucleus.
Along with the paramedian formation, it makes a kind of capsule around the medial nucleus ("circular nucleus").
The medial vestibular nucleus is one of the vestibular nuclei.
