What part of the brain is associated with fear?
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. For example, the amygdala activates whenever we see a human face with an emotion.
What is fear and how does it work?
Fear starts as a response to some action, event or situation. It usually starts in the part of the brain called the amygdala. There are two amygdalae and both of them work together to create the response to the action, event or situation. The amygdala is in the temporal lobe of the brain and is the core for triggering the emotion called fear.
How does fear spread to the body?
When the fear starts spreading to the body from the brain, a person is forced to choose between fight or flight responses. Fear starts as a response to some action, event or situation. It usually starts in the part of the brain called the amygdala.
How do the hippocampus and prefrontal cortex help interpret the perceived threat?
The hippocampus and prefrontal cortex help the brain interpret the perceived threat. They are involved in a higher-level processing of context, which helps a person know whether a perceived threat is real. For instance, seeing a lion in the wild can trigger a strong fear reaction,…
What happens to our brains when we are exposed to threats?
When they are exposed to threats, neural activity in the amygdala increases, and body responses (like sweating or increased heart rate) result. This is true even if the threatening stimuli are presented subliminally, such that the person is not consciously aware that the threat is present and does not consciously experience (feel) “fear.”
What happens to the amygdala when it is damaged?
The Interpretation: Since damage to the amygdala eliminates behavioral responses to threats, feelings of “fear” are products of the amygdala. People are indeed less responsive to threats when the amygdala is damaged (in humans amygdala damage can occur as a result of epilepsy or other medical conditions or their surgical treatment).
