2. Connections

To perform its many duties, the amygdala communicates with other areas of the brain and the nuclei within itself. For example, the amygdala can receive inputs from sensory organs; the olfactory bulb and olfactory cortex send scent inputs here. The nuclei within the amygdala take these inputs and formulate a response. The amygdala's additional involvement in the formation of emotional memories may explain why we recall specific events after smelling a certain scent.
