Consciousness depends on complex, irreversible brain dynamics that produce entropy. By fitting a statistical model to fMRI data and calculating entropy production, researchers found a monotonic relationship: entropy production decreases as people move from wakefulness to deep sleep. This suggests that entropy production is a robust signature of consciousness, linking conscious states to the thermodynamic activity of the brain.
