Synchronization, Information, and Brain Dynamics in Consciousness Research

Applied Sciences January 27, 2026 Francisco J. Esteban, Eva Vargas, José A. Langa et al.

Consciousness can be understood through a dynamical view of brain processing that combines three complementary frameworks: continuous formulations of Integrated Information Theory, attractor-landscape modeling of brain-state transitions, and perturbational complexity metrics from TMS-EEG. Consciousness emerges near criticality, where metastable attractors allow flexible transitions between partially synchronized states. Perturbational-complexity indices quantify the brain's capacity for integration and differentiation even without behavioral responsiveness. Across anesthesia, disorders of consciousness, epilepsy, and neurodegeneration, TMS-EEG biomarkers show reduced complexity and altered synchronization consistent with structural and functional disconnection. Integrating multimodal data supports individualized modeling of consciousness-related dynamics.
