Oxytocin hormone promotes bonding

Gazing into your lover's eyes isn't only romantic; it may also mimic early attachments that forever alter your brain and body.

Researchers at the University of California, San Diego (UCSD) School of Medicine are studying whether the brain hormone released with touches, hugs, or when a mother and her newborn baby bond might help patients with schizophrenia, social anxiety and a variety of other disorders.

Oxytocin is a brain chemical associated with pair bonding, including mother-infant and male-female bonds, increased paternal involvement with children, and monogamy in certain rodents, according to Kai MacDonald, M.D., assistant clinical professor of psychiatry at UCSD.

In humans, oxytocin is released during hugging and pleasant physical touch, and plays a part in the human sexual response cycle. It appears to change the brain signals related to social recognition via facial expressions, perhaps by changing the firing of the amygdala, the part of the brain that plays a primary role in the processing of important emotional stimuli. In this way, oxytocin in the brain may be a potent mediator of human social behavior.

“That's why oxytocin is sometimes called ‘the love hormone,'”said MacDonald. “It's said that the eyes are the window to the soul…they certainly are the window to the emotional brain. We know that the eye-to-eye communication—which is affected by oxytocin—is critical to intimate emotional communication for all kind of emotions – love, fear, trust, anxiety.”

    I used to take care of a older Gentleman in his 70's with schizophrenia and just a simple handshake or holding his hand for a few minutes would calm him down and redirect his mind to more positive things. This would have to be done 3-4 times throughout my shift depending on the day.
