Hippocampal dysfunction and cognitive impairments provoked by chronic early-life stress involve excessive activation of CRH receptors. Social vocalizations can release oxytocin in humans. Physically abused children also more readily categorize faces that are morphed between two different emotions as angry [126] and require less perceptual information to identify faces as angry than non-maltreated children [124]. 2010;34(10):73441 Available from: https://www.sciencedirect.com/science/article/pii/S0145213410002127.
