System And Method For Adjusting The Intensity Of Sensory Stimulation During Sleep Based On Sleep Spindles
The present disclosure pertains to a system configured to adjust an intensity of sensory stimulation delivered to a subject during a sleep session based on sleep spindles in the subject during the sleep session. The system is configured to adjust the intensity of the stimulation based on a sleep spindle frequency and/or a sleep spindle density. The system is configured to determine a recent spindle density and/or a recent spindle frequency for a recent period of time during the sleep session based on detected sleep spindles, and to determine a previous spindle density and/or a previous spindle frequency for a previous period of time during the sleep session based on the detected sleep spindles. The system controls the intensity of sensory stimulation provided to the subject based on a comparison of the previous spindle density to the recent spindle density and/or the previous spindle frequency to the recent spindle frequency.

- 1. A system configured to adjust an intensity of sensory stimulation delivered to a subject during a sleep session, the system comprising:
one or more sensory stimulators configured to provide sensory stimulation to the subject; one or more sensors configured to generate output signals conveying information related to sleep spindles in the subject during the sleep session; and one or more physical computer processors configured by computer readable instructions to:
detect the sleep spindles in the subject based on the output signals;
determine a recent spindle density and/or a recent spindle frequency for a recent period of time during the sleep session based on the detected sleep spindles;
determine a previous spindle density and/or a previous spindle frequency for a previous period of time during the sleep session based on the detected sleep spindles, wherein a beginning of the previous period of time occurs before a beginning of the recent period of time during the sleep session; and
control the one or more sensory stimulators to adjust the intensity of sensory stimulation provided to the subject based on a comparison of the previous spindle density to the recent spindle density and/or the previous spindle frequency to the recent spindle frequency, wherein controlling the one or more sensory stimulators includes increasing the intensity of the sensory stimulation responsive to an increase in the recent spindle density relative to the previous spindle density.
- 6. A method for adjusting an intensity of sensory stimulation delivered to a subject during a sleep session with an adjustment system, the adjustment system comprising one or more sensory stimulators, one or more sensors, and one or more physical computer processors, the method comprising:
providing sensory stimulation to the subject with the one or more sensory stimulators; generating, with the one or more sensors, output signals conveying information related to sleep spindles in the subject during the sleep session; detecting, with the one or more physical computer processors, the sleep spindles in the subject based on the output signals; determining, with the one or more physical computer processors, a recent spindle density and/or a recent spindle frequency for a recent period of time during the sleep session based on the detected sleep spindles; determining, with the one or more physical computer processors, a previous spindle density and/or a previous spindle frequency for a previous period of time during the sleep session based on the detected sleep spindles, wherein a beginning of the previous period of time occurs before a beginning of the recent period of time during the sleep session; and controlling, with the one or more physical computer processors, the one or more sensory stimulators to adjust the intensity of sensory stimulation provided to the subject based on a comparison of the previous spindle density to the recent spindle density and/or the previous spindle frequency to the recent spindle frequency, wherein controlling the one or more sensory stimulators includes increasing the intensity of the sensory stimulation responsive to an increase in the recent spindle density relative to the previous spindle density.
- 11. A system configured to adjust an intensity of sensory stimulation delivered to a subject during a sleep session, the system comprising:
means for providing sensory stimulation to the subject; means for generating output signals conveying information related to sleep spindles in the subject during the sleep session; means for detecting the sleep spindles in the subject based on the output signals; means for determining a recent spindle density and/or a recent spindle frequency for a recent period of time during the sleep session based on the detected sleep spindles; means for determining a previous spindle density and/or a previous spindle frequency for a previous period of time during the sleep session based on the detected sleep spindles, wherein a beginning of the previous period of time occurs before a beginning of the recent period of time during the sleep session; and means for controlling the means for providing sensory stimulation to adjust the intensity of sensory stimulation provided to the subject based on a comparison of the previous spindle density to the recent spindle density and/or the previous spindle frequency to the recent spindle frequency wherein controlling the means for providing sensory stimulation includes increasing the intensity of the sensory stimulation responsive to an increase in the recent spindle density relative to the previous spindle density.
