Is the amygdala responsible for anxiety?

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.

What emotions does the amygdala control?

Amygdala. The amygdala helps coordinate responses to things in your environment, especially those that trigger an emotional response. This structure plays an important role in fear and anger.

What does damage to the thalamus cause?

Damage to a portion of the thalamus is associated with risk of coma. Damage in a portion of the thalamus can lead to sensory changes in a body part. Damage here can also cause movement disorders, lack of movement (motor disturbances).

What effect might damage to the amygdala have on a person’s relationships with others?

People tend to choose avoiding losses over acquiring gains—a behavior known as loss-aversion.
