The so-called "love hormone" oxytocin does more than help us cuddle- new research at New York University indicates that oxytocin helps people distinguish between relevant and unimportant details in the world around us. The new results, published in Nature, show that oxytocin acts on a specific kind of hippocampal nerve cell known as inhibitory interneurons, which tell their neighbors to quiet their activity. But oxytocin didn't muffle all neuron signals, just those that essentially responded to background noise. Oxytocin had the opposite effect on pyramidal neurons that respond to novel stimuli were unaffected, which gives the brain additional abilities to sift through unimportant environmental details for what is really important. Besides providing an improved understanding for how the brain functions, this work also may help scientists understand conditions with abnormal oxytocin responses, such as autism.
