Abstract

Neuronal circuitry of anxiety The amygdala, a brain region important for learning fearful memories, is thought to have a role in generalized anxiety, but the subregions and connections involved in this response are unknown. Now, using optogenetic stimulation of basolateral amygdala terminals in the central nucleus of the amygdala of rats, a specific circuit for natural bidirectional anxiety control has been identified. Stimulating these neurons has a calming effect, whereas blocking the same projection increases anxiety-related behaviours. These findings are consistent with a role for the central nucleus of the amygdala in anxiety, although there may be other circuits working in parallel or downstream of the amygdala.
