Of course evolution is a fact. Have I given any indication of denying it?

Everyday Stress Can Shut Down the Brain's Chief Command Center

Neural circuits responsible for conscious self-control are highly vulnerable to even mild stress. When they shut down, primal impulses go unchecked and mental paralysis sets in.

Freezing under stress, a common experience for all of us at some point in our life, has its roots in a loss of control over “executive functions” that allow us to control our emotions.

Prefrontal cortical areas, which serve as the brain’s executive command centers, normally hold our emotions in check by sending signals to tone down activity in primitive brain systems.

Under even everyday stresses, the prefrontal cortex can shut down, allowing the amyg­dala, a locus for regulating emotional activity, to take over, inducing mental paralysis and panic.

Researchers are probing further the physiology of acute stress and are considering behavioral and pharmaceutical interventions to help us retain composure when the going gets tough.
