What does meeting an old friend, playing with your child and hugging your dog all have in common? Social interaction. A specific brain circuit is working hard behind the scenes to create and reinforce such interactions. Psychology professor Stephanie Preston evaluates research conducted by Stanford University professor Robert Malenka and his colleagues. It studies mice to understand the brain mechanisms involved in social behavior. The findings suggest that the neuropeptide oxytocin modulates excitability and the release of the neurotransmitter dopamine. getAbstract recommends Preston’s analysis to those who are interested in social interaction and its relation to neuroscience.
