Biology of trust that allow OT, AVP, and DA to exert their effects in high and low level processes in the brain that provide a foundation for social trust. In studies with human subjects who experienced social isolation, there was an increase in activity in the hypothalamic-pituitary-adrenal (HPA) axis-a neural network involved in the release of cortisol, a stress-response hormone.
