Chipmunk100 writes In a research article in the journal Cell scientists report that there is a subset of neurons that are vital in social interest of female mice for males during estrus, the sexually receptive phase of their cycle. They say that these neurons are responsive to oxytocin. The level of oxytocin rise when we hug or kiss a loved one. The BBC has an article on the findings as well, and reports that Without [oxytocin], female mice were no more attracted to a mate than to a block of Lego ... [The affected] neurons are situated in the prefrontal cortex, an area of the brain important for personality, learning and social behaviour. Both when the hormone was withheld and when the cells were silenced, the females lost interest in mating during oestrous, which is when female mice are sexually active.
