Study Arms:
- Health Subjects in Sleep Lab (Type: OTHER): Adult patients (\> 18yrs old) scheduled for a standard of care PSG (sleep study) lasting at least 8 hours for any condition. Patients will undergo simultaneous 2-lead limited EEG recording with experimental device. 2-lead limited electroencephalography recording
- ICU patients, not sedated or ventilated (Type: OTHER): Adult ICU patients (\> 18yrs old) anticipated to stay in the ICU overnight (minimum 8 hours) with a Glasgow Coma Scale of 13 or greater, not intubated and not sedated. Patients will undergo simultaneous 2-lead limited electroencephalography recording
- ICU patients, sedated and ventilated (Type: OTHER): Adult ICU patients (\> 18yrs old) who are intubated, sedated, ventilated, and anticipated to stay in the ICU overnight (minimum 8 hours). Patients will undergo simultaneous 2-lead limited electroencephalography recording
