The hippocampus is one of the structures of the [[limbic lobe]], first described by [[Paul Broca|Broca]] in 1878, as the cortical areas that line the deep edge of the cortex.<ref name="Purves2">{{cite book|title=Neuroscience|date=2012|publisher=Sinauer|isbn=978-0-87893-695-3 |edition=5th|location=Sunderland, MA|page=652| vauthors = Purves D }}</ref> The limbic lobe is the main component of the [[limbic system]].<ref name="Roxo">{{cite journal | vauthors = Roxo MR, Franceschini PR, Zubaran C, Kleber FD, Sander JW | title = The limbic system conception and its historical evolution | journal = TheScientificWorldJournal | volume = 11 | pages = 2428–2441 | year = 2011 | pmid = 22194673 | pmc = 3236374 | doi = 10.1100/2011/157150 | doi-access = free }}</ref> The [[cingulate gyrus]], and the [[parahippocampal gyrus]] are the two main parts of the described lobe, which had been largely associated with [[olfaction]].<ref name="Purves2"/> Many studies later culminating in work by [[Papez]], and [[Paul D.

MacLean proposed that the associated structures of the limbic lobe be included in what he termed as the ''limbic system''.<ref name="Roxo"/>
