Brain Criticality - Class 1

Explore the fundamental concepts of brain criticality in this 82-minute lecture from the ICTP-SAIFR School on biological physics across scales. Learn from Mauro Copelli of the Federal University of Pernambuco as he introduces the theoretical framework of critical phenomena in neural systems, examining how the brain operates at the edge of chaos between order and disorder. Discover the mathematical foundations underlying neural criticality, including phase transitions in neural networks, avalanche dynamics, and the emergence of scale-free behavior in brain activity. Understand how critical dynamics optimize information processing, enhance computational capacity, and facilitate efficient signal transmission across neural networks. Examine experimental evidence supporting the criticality hypothesis in various brain regions and scales, from individual neurons to large-scale cortical networks. Investigate the relationship between critical dynamics and cognitive functions, learning processes, and neurological disorders. This foundational class provides essential background for understanding how statistical physics principles apply to complex biological systems, particularly in the context of neural computation and brain function.
