#134 - Origins of The Human Brain: A Dialogue with William A. Harris

In this episode, Xavier Bonilla has a dialogue with William Harris about the origins of the human brain. They discuss the evolutionary history of the brain, rise of the neuron, and genesis of the neural tube and neuroepithelium. They talk about the phylotypic stage, neural stem cells to neurons, and four cycles of the cell. They discuss the important neuron theory, contributions of Ramon y Cajal, and how neurons "wire up." They talk about growth cones, Sperry's theory of neural connections, cell death, neural plasticity, and many other topics. William A. Harris is professor emeritus of anatomy at the University of Cambridge. He is also a fellow of the Royal Society, Academy of Medical Sciences, and was awarded the Waddington Medal by the British Society for Developmental Biology for his specialization on the visual system in the human brain. He is widely published within the scientific literature and author of many books including his most recent book, Zero to Birth: How the Human Brain is Built.  Get full access to Converging Dialogues at convergingdialogues.substack.com/subscribe
