Topic: mTOR over-activation

Several anxiety-related neuropsychiatric disorders are associated with amygdala dysfunction during early periods of postnatal development, and adolescence is a particularly vulnerable emotional period. Among the cellular mechanisms involved in changes in the activity of individual neurons and their synaptic connections, the mTOR signaling pathway has been proposed as a molecular regulator of emotional memories and could thus constitute a common mechanistic source of the emergence of anxiety symptoms in these disorders. We hypothesize that amygdala mTOR dysfunction during infancy can initiate a
