Triune brain

Marco Zagal, when he names "reptilian brain", "limbic brain" and "neocortex" is referring to this classification model of the human brain proposed by Dr. Paul MacLean and called triune brain. The triune brain is an alternative subclassification of the human brain used to explain the evolutionary functions. It is divided into three: reptilian brain, limbic brain and the neocortex. The reptilian brain and the limbic brain are recognized as the rational brain, while the neocortex is identified as rational brain. These "three brains" are interrelated and all form an integral part for the good health state beginning with the amygdala in the limbic brain, which determines our reactions through emotional self-control that is exercised from the neocortex or rational brain. All this affects the reptilian brain, indicative of our physical health status (fever, balance, breathing ...). Reptilian brain It regulates involuntary body functions such as temperature, balance, breathing, etc. and is responsible for the most primitive part (stimulus-response). It does not reach levels as complex as mental thought or emotion. Limbic brain It is where the amygdala, responsible for storing our emotions and memories, i.e., affective memory: jealousy, hate, maternal love, social relationships, etc. Neocortex It is what allows us to control our emotions and consciousness through the use of reason. Here our cognitive capacities develop: memory, attention, thought, concentration, conflict resolution, decision making, etc.
