Stress Social Deficits Reversed by Amygdala-Oxytocin Circuit Suppression
A 2026 mouse circuit study found that restraint stress progressively reduced medial prefrontal social coding: mPFC excitatory-neuron transient rates fell to roughly 70-80% of baseline after acute stress and nearly 50% after chronic stress, while suppressing either basolateral-amygdala input or hypothalamic oxytocin input restored social discrimination and behavior.1 The result is a circuit-specific oxytocin finding, …
