Amygdala Mistakes

Phobias are abnormalities in the brain according to neuroscientist researches. The function of amygdala we learned, as well as the prefrontal cortex in the brain, transmits chemical signals or nerve impulses to the brain to alert them of possible danger. The amygdala is found inside each cerebral hemisphere. The cerebral hemispheres also play certain roles in experiencing emotions. The Amygdala is rough and shaped like an almond of grey matter. However, like humans, amygdala too makes mistakes when alerting a person to danger. These mistakes are commonly known as False positive and False negative.
False positive: This mistake occurs when there is no danger but the amygdala still sends chemical signals to alert the brain that there is danger.
