Summary

New advances in Neuroscience have resulted in the development of predictive markers of different conscious states.

The earliest example was the Perturbational complexity index, developed by Massimini et al.

Key ideas

Anticorrelations

• Loss of consciousness suppresses anticorrelations between brain regions
• Psychedelics suppress anticorrelations between brain regions
• anticorrelations are not uniform in time

Structural-functional similarity

• Structural-functional similarity corresponds to states of consciousness

Entropy

• Entropy predicts different conscious states
• Perturbational complexity index
