Feasibility of mindBEAGLE in Disorders of Consciousness or Locked-In Syndrome

The primary aims of this study are: 1. To determine the feasibility of deploying mindBEAGLE, a portable, bedside EEG-based system, in the Intensive Care Unit in patients with disorders of consciousness (DOC) or locked-in syndrome (LIS); 2. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with bedside behavioral assessments of consciousness; 3. To determine if mindBEAGLE neurophysiologic markers of cognitive function correlate with functional MRI (fMRI) and electroencephalography (EEG) biomarkers of consciousness; 4. To determine if mindBEAGLE can serve as an assistive communication device for people with LIS.
