Andrew Huberman describes the biological basis of emotions and moods in human relationships. He examines the science of how early infant-caregiver attachment, along with adolescence and puberty shape our adult attachment patterns. As a part of the explanation, he talkes about the three universal aspects of emotions, the reality of right-brain and left-brain personalities, as well as specific aspects of puberty that contribute to the roots of adult attachment. Further, Andrew discusses how oxytocin and other chemicals impact how we perceive and remember others, as well as what determines when puberty begins and ends. His approach includes new tools for understanding and predicting our emotions before they occur, as well as neurochemicals that influence human connection.
