Figure 1.

Neural circuits (inputs and outputs) of oxytocin (OXT) and arginine vasopressin (AVP). Blue arrows indicate OXT and AVP neuronal inputs, while red arrows indicate OXT and AVP neuronal outputs. Combined blue and red arrows indicate regions that share both inputs and outputs. HYP refers to hypothalamic regions outside the paraventricular nucleus (PVN) and supraoptic nuclei (SON) of the hypothalamus. A, PVN and SON OXT neurons. B, PVN and SON AVP neurons. C, Sexually dimorphic AVP neurons within the bed nucleus of the stria terminalis (BNST) and medial amygdala (MeA).
