The confusing thicket of connections between neurons renders the brain a complex system. We have embarked on deducing how the subjective experience of vision emerges from the interaction of billions of neurons. Picking up mathematical tools from established studies of complexity, we infer network properties from the statistics of neural activity in cerebral cortex during visual processing. Specifically, I will present evidence for the notion that brain circuits self-organize to operate at a point of optimized signal processing, including during intense visual stimulation.
