1. How the Brain Creates the Body: Whose Leg is This? (Part 1)
In this inaugural episode, Hedi sits down with veteran science writer Moheb Costandi about his fascinating book Body Am I: The New Science of Self-Consciousness.From phantom breasts and rubber hands to the Pinocchio illusion and out-of-body experiences; from amputating a healthy leg to feel whole, to scratching an itch with a ghostly third arm – prepare to journey through the strange and astonishing ways our brains construct a sense of bodily self. Moheb walks us through the science, the syndromes, and the people whose experiences reveal just how malleable – and downright bizarre – our sense of owning a body really is.Relevant links:Book – Body Am I: The New Science of Self-Consciousness by Moheb CostandiMore about MohebChapters:(00:00) Losing a Limb to Feel Whole(01:12) Introduction(03:36) Understanding Bodily Awareness(04:41) A Hand That Isn’t Mine vs. A Hand I Can’t Control(05:51) Phantom Limbs, Breasts, and Beyond(08:26) Phantom Sensations in Transgender Individuals(09:49) Counting with Invisible Fingers(11:14) Therapies for Phantom Pain(12:50) Rubber Hands, Rubber Tails: The Illusion from Humans to Mice(16:34) Hammers, Knives, and Illusions in the Pub(18:32) Body Integrity Identity Disorder(21:08) A Surgeon, a Pistol, and a Leg(22:02) Hemiplegia and The Denial of Paralysis(23:36) Discovering Body Maps in the Brain(26:58) Scratching an Itch with a Ghostly Third Arm(29:02) The Multisensory Mind(30:13) Inducing Out-of-body Experiences(31:50) The Body Swap Illusion(32:35) The Barbie Doll Illusion(33:49) Proprioception and the Pinocchio Illusion(35:00) The Story of Ian Waterman(36:20) Interoception and the Origins of Emotion(39:21) Alexithymia and Emotional Blindness(39:56) Wrapping Up & What’s NextEpisode Credits:Creator & Series Producer: Hedi YoungConcept Development & Curation: Ana Rita Mendes, António Monteiro, Carla Emilie Pereira, Catarina Ramos, Diana Cadete, Hedi Young, João Van Zelst, John Lee, Marta Correia, Thaïs Lindemann and Teresa FernandesHost: Hedi YoungGuest: Moheb CostandiGraphic Design: Marta CorreiaSound Design: João Van ZelstDissemination: Ana Rita Mendes and Diana Cadete
