The limbic system is a complex system that consists mainly of the limbic lobe, cortical areas and subcortical nuclei that have connections to the limbic lobe.
Key structures of the limbic system include:
- cingulate gyrus
- basolateral nuclei of the amygdala
- septal nuclei
- nucleus accumbens
- hypothalamus (mammillary bodies)
- anterior nucleus of the thalamus
History and etymology
It was first called "le grand lobe limbique" by Pierre Paul Broca (1824-1880), a French physician, in 1878 . Broca believed that the main role of the "limbic lobe" was the perception of smell.
Limbic is Latin for "border". In this case, the border is between the neocortex and the subcortical structures (diencephalon).
