Detecting higher cortical function in patients with pervasive vegetative or minimally conscious state with qEEG coherence

It is possible that some of these patients suffer from motor deficits that deprive them the ability to express themselves, but have some remaining perceptual abilities that cannot be observed. To date, such perceptual abilities have been detected with the use of Event Related Potentials (ERPs). The present study presents pilot data of an alternative method with the use of electroencephalic (EEG) coherence.
