Abstract: The present disclosure pertains to a system and method for determining and displaying a sleep restoration level of a subject for a target sleep session. In some embodiments, the system comprises one or more of a sensor, a processor, electronic storage, a user interface, and/or other components. As the subject sleeps, the system is configured to determine a metric indicating sleep need for the subject and then graphically display a sleep restoration level (a visual representation of the metric indicating sleep need) based on the determined sleep need metric. Instead of assuming common parameters for multiple users, the system is configured to determine the sleep need metric based on obtained baseline sleep parameters that have been determined individually for the subject based on one or more previous sleep sessions, a determined amount of slow wave activity in the subject during the target sleep session, and/or other information.

Abstract: Systems and methods for providing sensory stimuli induce and/or enhance sleep and/or slow wave neural activity of a subject during sleep. Operation of the systems and methods is based on measured information related to cardiac attributes and/or respiratory attributes of the subject, and corresponding cardiac parameters and/or respiratory parameters based thereon. Attributes may be measured and/or monitored via one or more sensors, e.g. worn on an extremity of the subject and/or placed at a distance from the subject. Sensory stimulation delivered to the subject during specific targeted periods of sleep may enhance slow wave neural activity.

Abstract: A system is configured to provide sensory stimuli to a subject at a first intensity level, determine the effectiveness of the provided sensory stimuli, and incrementally increase the intensity level of the sensory stimuli based on the determined effectiveness. The effectiveness determination and the corresponding intensity increase are repeated one or more times during a given slow wave sleep episode. The system is configured to continue the effectiveness determinations and the corresponding intensity increases during the slow wave sleep episode until the intensity level reaches a maximum level, until an arousal level of the subject breaches an arousal level threshold, and/or until expiration of the period of slow wave sleep.

Abstract: The present disclosure pertains to a system and method for managing a sleep session of a subject. Managing the sleep session is based on slow wave activity in the subject during the sleep session. Slow wave activity is related to sleep pressure. Sleep pressure dissipates and/or decreases as the subject sleeps. The dissipation dynamics depend on a given subject. The manner in which dissipation occurs regulates the length of the given sleep session and is linked to the temporal dynamics of slow wave activity. The system is configured to determine a metric indicating sleep pressure dissipation and, responsive to the determined sleep pressure dissipation metric indicating that sleep pressure dissipation has reached a dissipation threshold level during the sleep session, wake the subject.

Abstract: The present disclosure pertains to a system and method for managing a sleep session of a subject. Managing the sleep session is based on cardiac activity in the subject during the sleep session. Cardiac activity, as monitored via one or more sensors worn on an extremity of the subject and/or placed at a distance from the subject, is used to determine periods of slow wave sleep. Sensory stimulation is delivered to the subject during the periods of slow wave sleep to enhance slow wave activity. Wearing a sensor on an extremity, and/or placing a sensor at a distance from the subject during sleep, as opposed to the subject wearing an EEG cap, is more comfortable for the subject.

Abstract: The present disclosure pertains to a system for enhancing knowledge consolidation in a subject during sleep. New declarative memories may be better consolidated by presenting sensory stimuli during slow wave sleep that correspond to sensory stimuli presented during prior wakeful learning. The sensory stimuli may include odors, sounds, visual stimulation, touches, tastes, and/or other types of sensory stimuli. The system is configured to provide a prompt sensory stimulus during slow wave sleep that corresponds to a wakeful stimulus provided during wakeful learning. The prompt sensory stimulus may prompt enhanced knowledge consolidation in the subject. In some embodiments, the system may comprise one or more of a slow wave sleep inducer, a sensory stimulator, a sensor, a processor, electronic storage, a user interface, and/or other components.

Abstract: Systems and methods for delivering stimuli to a subject that prompt the subject to fall asleep use multiple parameters that are based on measured signals related to a patient's brain activity, for example obtained through electroencephalography (EEG). The parameters indicate amplitude in different frequency bands, e.g. high-frequency brain activity and low-frequency brain activity. A stimulus, e.g. auditory stimulus, is delivered to the subject such that the intensity of the stimulus is adjusted based on (changes in) the multiple parameters.
