Limbic cortex

Brain: Limbic lobe
Latin lobus limbicus
NeuroNames NeuroLex ID birnlex_1128

The limbic lobe is an arc-shaped region of rhinal sulcus, and omits the hippocampus.

Broca named the limbic lobe in 1878, identifying it with the cingulate and parahippocampal gyri, and associating it with the sense of smell - Treviranus having earlier noted that, between species, the size of the parahippocampal gyrus varies with the size of the olfactory nerve.[2] In 1937 Papez theorized that a circuit including the hippocampal formation and the cingulate gyrus constitutes the neural substrate of emotional behavior,[3] and Klüver and Bucy reported that, in monkeys, resection involving the hippocampal formation and the amygdaloid complex has a profound effect on emotional responses.[4][5] As a consequence of these publications, the idea that the entire limbic lobe is dedicated to olfaction receded, and a direct connection between emotion and the limbic lobe was established.[6]
