Brain ans stress response


FIGHT-OR-FLIGHT RESPONSEūü߆

.

When someone experiences a stressful event, the amygdala, an area of the brain that contributes to emotional processing, sends a distress signal to the hyppocampus. This area of the brain functions acts like a command center, communicating with the rest of the body through the nervous system so that the person has the energy to fight or flee to survival.

.

This ‚Äúfight-or-flight‚ÄĚ response is responsible for the outward physical reactions most people associate with stress including increased heart rate, heightened senses, a deeper intake of oxygen and the rush of adrenaline.

.

Finally, a hormone called cortisol is released, which helps to restore the energy lost in the response.

.

When the stressful event is over, cortisol levels fall and the body returns to stasis. In addition to restoring balance to the body after a stress event, cortisol helps regulate blood sugar levels in cells and has utilitarian value in the hippocampus, where memories are stored and processed.
