What index is used in clinical neurology to measure the brain's capacity for complex, integrated responses in patients with disorders of consciousness?
Answer
The Perturbational Complexity Index (PCI)
PCI is calculated by applying TMS combined with EEG to measure the complexity of the resulting integrated response pattern, which correlates with the structural potential for consciousness.
