The Triune Brain

It is a model that conceptualizes the brain as having three functional domains: an ancient part of the brain for automatic regulatory functions, a region for emotions, and a recently evolved layer for cognition, memory storage, sensory processing, abstractions, philosophy, and navel contemplation.

According to MacLean, layer 2 is responsible for emotions and prompts the ancient layer 1 to generate responses based on emotional cues.

There is anatomical overlap between the layers, the flow of information is not just top-down, automatic behavior, emotion, and thought are not separable, and the model leads to the mistaken belief that new layers were just added on without changes to the existing ones.
