n an almond-shaped neural structure in the anterior part of the temporal lobe of the cerebrum; intimately connected with the hypothalamus and the hippocampus and the cingulate gyrus; as part of the limbic system it plays an important role in motivation and emotional behavior
It may turn out that some anxiety disorders are caused by an overactive amygdala (the accelerator) while others are caused by an underactive prefrontal cortex (call it the brake).
In addition to the amygdala, there are three other anatomical hot spots involved in the disorder: the orbital frontal cortex, the caudate nucleus and the thalamus--the first two .
If they do, the cortex signals the amygdala, and the body stays on alert.
