The expression of the oxytocin receptor was detected in a variety of brain areas where it participates in the regulation of different functions, e.g., amygdala (social behavior and fear), hippocampus (spatial memory and neurogenesis), prefrontal cortex (maternal, socio-sexual, and anxiety behavior), hypothalamus (homeostatic feeding), periaqueductal gray (anxiety-related behaviors), olfactory bulb (social behavior), striatum, ventral tegmental area, and nucleus accumbens (non-homeostatic food intake and reward) [19,26,27,28,29,30]. Here, OXTR is linked to Anxiety.
