Understanding how different states of consciousness arise from brain activity remains a central challenge in consciousness science. Theoretical and empirical work has increasingly linked conscious states to the large-scale organization and dynamical complexity of brain activity, using measures ranging from network integration and graph-theoretical properties to signal diversity, perturbational...
Brain waves are ubiquitous phenomena of human brain activity. As they propagate, they coordinate neural communication, shaping conscious perception. Understanding how brain waves unfold across space and time is thus critical for uncovering the neural mechanisms that support and suppress consciousness. Here, we analyzed data from the Human Connectome Project alongside multiple independent human...
Anesthesia has revolutionized surgical practice and offers a controlled model to study the neurobiology of consciousness. Functional magnetic resonance imaging (fMRI) studies have shown that anesthesia primarily disrupts connectivity across association cortices, suggesting that impaired integration between higher-order brain regions underlies unconsciousness. However, traditional fMRI paradigms...
