Integrating the Triune Brain via Floating
In Michael Hutchinson’s book, “The Book of Floating; Exploring the Private Sea”. He talks about how regular floating integrates and creates neural networks of communication between the different parts of the Truine Brain.
So what are these parts and what do they do?
The Reptilian Brain (RAS) is the part of the brain located in the back of the head and it connects to the spine. “It is the part of the human brain that coldly watched and waits, stays alert or nods off to sleep. It is the “alarm bell of the brain,” which determines our arousal level and our state of awareness or attention. The reptilian brain plays a crucial role in determining how outgoing and social, or indrawn and shy, we are.” People who’s RAS is quite open may feel overstimulated and be seen as more of an introvert whereas people who’s RAS filter’s out quite a bit of stimulation may feel the need for more stimulation and activities to feel alive. They therefore may be considered extraverts. Floating helps to balance and bring the body and brain into a place of homeostasis. This will help balance an overstimulated RAS and an understimulated RAS. This capacity of balance in this area may help someone to navigate both introversion and extroversion with more flow and without having to go to polar extremes. When all sensory input from the outside is gone, One can develop more hightened sensory input within their own body/mind and energetic field. One can also relax into a deep state of quiet.
The Paleomammalian Brain is in the central part of the skull and is the control center for one’s approach to life and emotions. “Here are generated all our vivid emotions and states of mind: rage, fear, panic, pleasure, bliss. This is the area in which sudden responses of affection, sexual behavior, parental attachment, altruistic impulses, and even love originate. These moods and emotions are in many ways inseparable from physiological responses in the autonomic nervous system (things that make us blush, flush with anger, heart pounding, sweaty and so forth). Ruling this part of the brain is the hypothalamus and anything that stimulates the hypothalamus affects the entire system. Floating has a very substantial effect on the hypothalamus. It has an enormous effect on the balance of mood, emotions, control over autonomic functions and all aspects of the mind-body interrelationship. “The limbic system responds to floatation by inhibiting the release of hormones and neurotransmitters that have a harmful or stressful effect, such as adrenaline and cortisol. At the same time, floating apparently caused the limbic system to increase the secretion of very beneficial neurochemicals such as endorphins.”
Lastly, the Neocortex is the “thinking cap” of the brain. The part of the brain that percieves abstract thought, cognitive functions, memory, judgment, intellect, visual and auditory perceptions, conscious thinking and language. Whereas the other parts of the brain are related to more “unconscious thinking, process, healing”, the neocortex is related to “conscious thinking”. It is incharge of our voluntary movements and actions. “floating allows the neocortex to become more aware of the operation of the limbic system and to assume conscious control over that system; by becoming aware of the effects of certain neurochemicals released by the limbic system, the neocortex can consciously learn to increase or decrease the secretion of those chemicals, much as someone hooked up to a biofeedback machine can learn to raise or lower her/his/zir own blood pressure.”
Floating supports the unification of all three brains working together for the benefit and the healing of the person floating!
