Measuring Integrated Information in Neural Systems
Neuroscience
Developing practical methods to compute Φ (phi) from neural recordings and test Integrated Information Theory predictions. Addresses computational intractability through approximations and identifies empirical signatures of consciousness.
Core Beliefs
Consciousness corresponds to integrated information (Φ) in causal systems
The quale of an experience is identical to its cause-effect structure
Systems with high Φ exist intrinsically from their own perspective
Methods
Approximation algorithms for computing Φ in large networks
Perturbational complexity index measurements during sleep/anesthesia
