Cortical synchrony changes detected by scalp electrode electroencephalograph as traumatic brain injury patients emerge from coma.

Background: Recent studies show conscious perception is correlated with firing rate synchronization across multiple neuronal assemblies. This study explores the synchrony between multiple cortical surface sites as brain injury patients emerge from coma.

Methods: Scalp electrode EEG recordings were collected and analyzed from 13 traumatic brain injury patients during their stay in a neurosurgical intensive care unit.
