Triune Brain – The Daily Concept

The Triune Brain is a model for the evolution of the vertebrates brain proposed by the American physician and neuroscientist Paul D. MacLean. The Triune Brain consists of the reptilian complex, the paleomammalian complex (lymbic system) and the neomammalian complex (neocortex).

The reptilian complex is responsible for instinctual behaviors involved in aggression, dominance, territoriality and ritual displays.

The paleomammalian complex is responsible for the motivation and emotion involved in feeding, reproductive behavior, and parental behavior, mutual reciprocity.

The neomammalian complex is responsible for the abilities of language, abstraction, planning and perception.
