In this episode, Dr. Huberman discusses the biology of emotions and moods in the context of relationships. He focuses on the science of how early infant-caregiver attachment, combined with adolescence and puberty shape our adult patterns of attachment. He explains the three universal aspects of emotions, the reality of right-brain versus left-brain personalities, and how the roots of adult attachment are also grounded in specific aspects of puberty. Dr. Huberman reviews what factors determine when puberty starts and ends, and the role of oxytocin and other chemicals in controlling how we perceive and remember others. As always, he refers to various practical tools including new tools for understanding and predicting our emotions before they occur, and neurochemicals that shape human connection.
