stress stimulates what part of the brain the reptilian brain
If the situation is judged as being stressful, the HYPOTHALAMUS (at the base of the brain) is activated. The hypothalamus in the brain is in charge of the stress response. When a stress response is triggered, it sends signals to two other structures: the pituitary gland, and the adrenal medulla. These short term responses are produced by The Fight or Flight Response via the Sympathomedullary Pathway (SAM).
