In essence, we are living with three brains, not one. Each of those brains developed in evolutionary time. The oldest of them is the Reptilian Brain. This part of the brain deals
with instinct, memory, and sustains basic life functions in the body. The Reptilian brain
regulates the bodies enormously complicated assorted functions, such as valves for blood
vessels, or the pumping of the heart, or even the selection of gastro-intestinal chemistries.

The Reptilian Brain is responsible for the flight or fight response, negative or dark emotions and simplistic emotional responses, and simple need tropisms like seeking out warmth or shelter or food or water.


The Mammalian Brain is slightly younger and evolved next. This part of us is responsible
for our social emotions, compassion, love, and social bonding.

The Cerebral coretex or frontal lobes or modern Brain is repsonsible for the ego mind,
social interactions, social identity, logical reasoning and intellectual faculties.

Each of these three areas of the brain ends up being in some ways an independant person. Each person is somewhat a multiple personality. 2 parts of us are subliminal
and seldom if ever does the conscious mind know that these parts of us are there. Both the mammalian Brain and the Reptilian Brain end up thinking and operating independantly of the frontal lobes.

Psychology and Psychonautics hinges upon how these three persons living in one head interact with each other (and how two of them hide from the third.)
