Explore the cutting-edge field of brain mapping in this 55-minute World Science Festival panel discussion. Delve into the ambitious Human Connectome Project as leading neuroscientists and psychologists discuss their efforts to map the intricate wiring of nearly 100 billion neurons in the human brain. Learn about the potential of the connectome to revolutionize treatments for psychiatric and neurological disorders, uncover the electrochemical roots of memory and behavior, and understand the link between upbringing and brain development. Discover key topics such as the definition of a connectome, the work of Santiago Ramón y Cajal, brain signaling, youth brain development, and the challenges of explaining brain function through current mapping techniques. Gain insights into the inspiration behind this groundbreaking research and explore the possibilities of developing new synaptic responses in adult brains.
