Consciousness transitions during epilepsy seizures through the lens of Integrated Information Theory

The paper examines how Integrated Information Theory (IIT) can be applied to understand changes in consciousness during epileptic seizures. IIT quantifies consciousness through a measure called phi, which reflects the brain's capacity for integrated information. The authors argue that different seizure types produce distinct disruptions in neural integration and information, correlating with varying degrees of consciousness impairment. Focal seizures may reduce phi in specific brain regions, while generalized seizures cause a widespread drop in integrated information, leading to loss of consciousness. The analysis suggests that IIT offers a useful framework for linking seizure activity to conscious experience.
