This model of brain structure and function is based on three specific regions of the human brain: the 1) basal ganglia, 2) the limbic system, and 3) the neocortex. MacLean's pioneering concept of "The Triune Brain" began to emerge in 1949 with his publication Psychosomatic disease and the "visceral brain", followed in 1952 by Some psychiatric implications of physiological studies on frontotemporal portion of limbic system (visceral brain).This shows that his seminal ideas grew out of his astute observation of psychiatric signs and symptoms. In his three-brain-in-one (triune brain) theory, MacLean (1970) suggested that there was the reptilian or primitive brain (possessed by fish, amphibians, reptiles, birds, and mammals), the limbic or paleomammalian brain (possessed by mammals), and the neocortical or "rational" neomammalian brain (possessed by a few MacLean, Paul.

Con la locuzione psicologia postmoderna generalmente si intende qualificare la diffusione di tutti quei nuovi orientamenti concettuali che hanno tracciato per la scienza psicologica uno sviluppo in direzione della complessità prospettica. Oldest and most primitive brain that controls breathing, heart beat and basic sensory motor functions like balance and muscles. Science. These interconnected brains are: 1. As the century ended, however, such efforts were lost in the surge of new effort in brain and genome research. A popular theory used to conceptualize brain functioning is the triune brain theory. The Take Away. MacLean's evolutionary triune brain theory proposed that the human brain was in reality three brains in one: the reptilian complex, the limbic system, and the neocortex. MacLean's triune brain theory suggests that the human brain comprises three basic formations, known as the reptilian complex, the paleomammalian complex (corresponding to the limbic system) and the neomammalian complex (corresponding to the neocortex), and proposes that these formations reflect the evolution of reptiles, lower mammals, and .

Probably the best known model for understanding the structure of the brain in relation to its evolutionary history is the famous triune brain theory, which was developed by Paul MacLean and became very influential in the 1960s.
