What is the reptile brain in humans?

Which part of brain can be removed?

Hemispherectomy is a very rare neurosurgical procedure in which a cerebral hemisphere (half of the upper brain, or cerebrum) is removed, disconnected, or disabled.

Can you live without an amygdala?

What does a damaged amygdala do?

Understanding Damage to the Amygdala The amygdala helps control our fear response, but it also plays a crucial role in many other cognitive functions. Therefore, damage to the amygdala can cause serious problems, such as poor decision-making and impaired emotional memories.

What disorders are associated with the amygdala?
