Neurobiology of a traumatic event
The brain stem is critical in fast, defensive responses. Its directly connected
with the retina.
the retina sends visual information to the brain stem immediately before
higher levels of the brain are even aware of the threat
If the predator moves close the XX initiates a fight or flight response
periaqueductal gray (in brain stem)
activates the sympathetic nervous system
heart rate goes up
blood flow to muscles increases
blood pressure increases
pupils dilate
If it isn't safe to fight or escape, a person may freeze or feigned death and
now the periaqueductal gray activates the
parasympathetic nervous system
muscles get tight and freeze
both gaze and breath may freeze
This is not a cognitive choice
decision is made at the brain stem and nervous system
