|Our Brain called the triune brain consists of 3 integral systems. The three parts are
commonly known as the reptilian brain (instinctual), the mammalian or limbic brain (emotional) and the human brain or neo-cortex (rational). Since
the parts of the brain that are activated by a perceived life-threatening situation are the parts we share with animals (reptilian Brain), much has been
learned by studying how animals avoid traumatization.
When an animal is faced with a life-threatening situation, adrenalin is pumped into the system to give enough energy to respond in a fight,
flight or freeze response. When the animal is out of danger, the system can get back onto balance by starting to engage in discharge behaviors like
shaking, twitching, etc. This is not arbitrary. Appearing like a re-enactment, for example, it could move like it's running to get away from a lion
fulfilling its initial response. Excess survival energy in the nervous system that has accumulated to initiate the fight, flight response can begin
The system has a chance to fully re-integrate.
