Explore the fascinating organization of the brain through this 56-minute lecture that delves into network theory and brain connectivity. Learn how the brain functions as an interconnected network of modular regions, each responsible for specific cognitive tasks like image processing and language. Discover key concepts in graph theory and their application to understanding brain connectomes, from basic neural networks in worms and flies to the complex architecture of the human brain. Examine important network properties including paths, connectivity, hubs, and the small-world effect that help explain how our brains learn and operate. The lecture, delivered by Royal Society Fellow and Oxford Centre Director Alain Goriely at Gresham College, concludes with insights into the future of network neuroscience and its implications for understanding brain function.
