What is the triune brain model proposed by Paul MacLean?
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.

What is the function of layer 2 of the triune brain model?
According to MacLean, layer 2 is responsible for emotions and prompts the ancient layer 1 to generate responses based on emotional cues.
What are some of the disadvantages of the triune brain model?
What are some of the disadvantages of the triune brain model?
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.
