Task 4 - oxytocin, brain physiology, and functional connectivity . Oxytocin (ot) received lot of attention due to potential to positively influence social behavior. Early studies examined how ot influences formation of social bondy, maternal behavior. Effects of ot partly regulated by gondal hormones oestrogen. Animal research provided indications of specific brain regions affected by ot driven by these findings, focus shifted to research into effect that ot administration has on human behavior trust, morality, self-perception and social emotional behavior. Aim of review: discuss effects and provide overview of current status two main methods: physiological research and neuroimaging. Emerging evidence suggests ot modulates neuronal communication throughout brain areas that play key role in social-emotional behavior. Oxytocin is secreted by pituitary gland and triggered by projections from hypothalamus, causing wide range of bodily reactions. Most effects not triggered directly because of blood- brain barrier.
