BRAIN (Triune) 5)

A three levels model of the brain.
This concept of a multilevel organization of the brain as a complex system was developed by P. Mac LEAN, as quoted by A.S. IBERALL: "At its base lies the reptilian brain, in which one might say the routines or rituals of higher forms of life are governed and programmed. Surrounding that structure is the paleomammalian brain, the limbic structure, sometimes referred to as the older "smell" brain. Out of this the governing of the world originating from smell, the worlds of food and sex and aggression are intermingled (and sometimes confused). Finally, at the top emerges the neomammalian brain, the brain of sight, the primate brain, the brain of cognition and language, and coordination of language… What is characteristic of the neocortex is its rapid response, particularly to sensory signals. It programs at the millisecond level. It devotes a considerable part of its capacity to handling optical signals" (1975, p.21).
This model of the globally integrated brain has also been considerably developed by the French physiologist H. LABORIT (1954 and 1970).
