Editing Triune brain (section)

===Paleomammalian complex===
This consists of the [[septum]], [[amygdalae]], [[hypothalamus]], [[hippocampus|hippocampal complex]], and [[cingulate cortex]]. MacLean first introduced the term "[[limbic system]]" to refer to this set of interconnected brain structures in a paper in 1952. MacLean's recognition of the limbic system as a major functional system in the brain was widely accepted among neuroscientists, and is generally regarded as his most important contribution to the field. MacLean maintained that the structures of the limbic system arose early in mammalian evolution (hence "paleomammalian", with ''[[wikt:paleo-|paleo-]]'' meaning ''old'') and were responsible for the motivation and emotion involved in feeding, reproductive behaviour, and parental behaviour.  {{Citation needed|date=September 2017}}
