The Triune Brain is divided into three sections: Reptilian, Paleomammalian and Neomammalian. MacLean proposed that the human skull doesn't just contain one single brain, according to his Triune Brain Theory, it in fact holds three. These three separate brains work interdependently, interconnected by nerves, each of which operate differently with different capacities. The Reptilian Brain was referred to by MacLean as the ‘R Complex’ or the primitive brain. This is t…
