Triune brain

The Triune Brain, is a hypothesis proposed by Paul MacLean about the traces of evolution existing in the structure of the human brain. The hypothesis conceives the brain as a system consisting of three subsystems, all of which originated from separate points of evolutionary history. The systems are therefore not in a state of perfect equilibrium, since they actually are three relatively independent systems constituting a bigger one.

The three systems are, in chronological order:

1) The R-complex

2) The Limbic system

3) The Neocortex
