Jungle brain

People entered this world one of two ways: they evolved from the jungle, or they escaped from the jungle. Unfortunately, the escapees far outnumber those who evolved. The ratio is about nine to one.

The brain of the escapee is controlled by the amygdala. This “jungle brain,” the small almond-sized growth on top of the brain stem, is the first to receive information from the five senses. It is the gatekeeper that controls information flow into the analytical or cognitive sector of the brain.

Jungle instincts, including what we call “gut feelings,” are the result of 600 million years of evolution. They are deeply ingrained and not easily changed. They are the same instincts animals from ants to antelopes have. They generate a powerful urge to form into colonies or herds. They want an alpha leader they can follow obediently and without question. They want a distinct hierarchy and accept their place in it.

Any challenge to the order is considered to be a threat to herd cohesion and the survival of the herd, colony or tribe. Challenges are dealt with harshly. At the human level, these rebels are given labels such as subversives, fifth-columnists or traitors and are deeply reviled. Punishing or even killing them is widely accepted.

Cognitive sector usurpation of the jungle brain information flow function is extremely difficult and rare. Only when that happens can a person have a soul or conscience.
