How does anxiety affect the amygdala?
The amygdala has a central role in anxiety responses to stressful and arousing situations. Pharmacological and lesion studies of the basolateral, central, and medial subdivisions of the amygdala have shown that their activation induces anxiogenic effects, while their inactivation produces anxiolytic effects.

How do I stop fight or flight response anxiety?
Exercise is therefore a simple and effective way to calm the nervous system. It not only uses the energy created in the body, it metabolises (breaks down) excess stress hormones. Lower levels of stress hormones mean a calmer body and mind.

Stress can induce various alterations of neurotransmission system in amygdala, mainly in GABA receptors adaption, the GABAergic inhibition and the synaptic neurotransmission. Lasting hyperactivity in amygdala might contribute to higher susceptibility to stress-related neuropsychiatric diseases.
