Dr Tara Swart reveals the surprising neuroscience behind love, attraction and relationships - from the hormones that drive bonding to the hidden signals our brains use when choosing a partner. She explains why oxytocin is so important for love and trust, how stress can affect our relationships, why smell can be a powerful attraction signal, and what happens in the brain when a new relationship becomes sexual. Tara also explores why delaying sex may help create stronger bonds, and how evolution continues to influence who we find attractive. We're Talking Relationship Neuroscience!
