Question

how does the brain reactin emergency situation​

Answer 1

Answer:

Long-term stress takes its toll on the human brain. It makes neural connections that strengthen emotions and help to form factual memories. Stress increases activity in the amygdala, an area of the brain associated with fear and anger.

Answer 2

Answer:

The cerebellum, or brain stem, is similar in structure to the reptilian brain and it controls the fight, freeze or flee responses when confronted with a crisis. The limbic system is in the mid area of the brain. It functions much like the brains found in other mammals and is responsible for emotional reactions.
