"Individuals who suffer from phobias have shown to display increased activity of the amygdala when exposed to phobia-inducing stimuli, noted on functional MRI. The amygdala is known to be associated with emotional reactions. The right amygdala is more highly reactive in response to negative emotions, such as those associated with phobias. Whereas the left amygdala is more strongly associated with pleasant emotional reactions. The height the activation of the right amygdala, the greater sense of distress induced by the phobia trigger.
The stria terminals, the anterior cingulate cortex and the insula were found to be hyper-activated in individuals who experienced sustained exposure to phobia inducing pictures in an experimental setting. "

"The amygdala is an almond-shaped set of neutrons located deep in the brains media temporal lobe. Key role is the processing of emotions. Conditionals such as anxiety, PTSD and phobias are suspected of being linked to abnormal functioning of the amygdala. "
