3. Persistent surgical mask use alters dopamine neurotransmission dynamics in the ventral striatum and amygdala via stress-dependent modulation of the noradrenergic system, thereby promoting conditioned avoidance learning in healthy adults. In particular this problematic behavior may induces cortisol-mediated anxiogenic effects by modulating stress-dependent dopamine D2 connectivity in the ventral striatum, thereby facilitating striatal-based memory retrieval while downregulating amygdala-hippocampal activity:
