Amygdala Volume

Meaning

Amygdala volume is a neuroanatomical metric quantifying the physical size of the amygdala, a pair of almond-shaped nuclei deep within the temporal lobes of the brain. This structure plays a central role in processing memory, decision-making, and emotional responses, particularly fear and anxiety. Variations in the size of this limbic system component have been clinically correlated with specific mood and stress-related disorders, often showing a sexually dimorphic pattern influenced by circulating steroid hormones. Clinicians in hormonal health consider this measurement relevant due to the intricate bidirectional communication between the endocrine system and the central nervous system.
