What is the Amygdala?

Updated December 04, 2013

Definition: The amygdalae are a pair of almond-shaped structures within the medial temporal lobes of the brain. The structures form part of the limbic system and are involved in emotional processing and memory. In particular, the amygdala is implicated in the fear response known as “fight or flight”. Anxiety disorders are believed to result in part due to anomalies in amygdala function.
