In this episode, we explore the human brain in love and grief and how research is being used to help people with social and emotional disorders. Renowned anthropologist and best-selling author Dr. Helen Fisher shares her decades of research on what happens to the human brain in love. Dr. Larry Young at Yerkes Primate Research Center has studied prairie voles for 25 years and his discoveries have helped us better understand what happens to the brain in love, separation and grief. Prairie voles are one of the few mammals that are monogamous for life. Young's research is being used to conduct clinical studies to see if we can treat people with autism spectrum disorder and mental health disorders, using intra-nasal sprays containing the molecules associated with connection and love.
