SYSTEM AND METHOD FOR DETERMINING SLEEP STAGES BASED ON CARDIAC ACTIVITY INFORMATION AND BRAIN ACTIVITY INFORMATION IN EEG SIGNALS

摘要

The present disclosure pertains to a system configured to determine sleep stages in a subject based on cardiac artifact information and brain activity information in EEG signals. Cardiac artifacts present in EEG signals can cause erroneous sleep stage determinations which may result in inopportune sensory stimulation during sleep, no stimulation at all, discarding long periods of EEG signal information, and/or other events. The present system enhances real-time sleep stage determinations compared to prior art systems and/or provides other advantages because the present system determines the current sleep stage of the subject based on both cardiac activity information and brain activity information included in the EEG signals.
