GENERAL HISTOLOGY

Detailed explanation-1: -The fear response starts in a region of the brain called the amygdala. This almond-shaped set of nuclei in the temporal lobe of the brain is dedicated to detecting the emotional salience of the stimuli – how much something stands out to us.

Detailed explanation-2: -The central nucleus of the amygdala also produces conscious perception of emotion primarily through the ventral amygdalofugal output pathway to the anterior cingulate cortex, orbitofrontal cortex, and prefrontal cortex. Stimulation of the amygdala causes intense emotion, such as aggression or fear.

Detailed explanation-3: -As soon as you recognize fear, your amygdala (small organ in the middle of your brain) goes to work. It alerts your nervous system, which sets your body’s fear response into motion.

Detailed explanation-4: -The amygdala is part of the brain’s limbic system. The limbic system consists of different parts of the brain: The hippocampus, which stores memories, and the amygdala, which processes fear, are the major players.
