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).
