System and method for determining timing of sensory stimulation delivered to a subject during a sleep session

A method for determining timing of sensory stimulation delivered to a subject during a sleep session with a determination system, the sensory stimulation configured to increase slow wave activity and minimize arousals in the subject during the sleep session, the system comprising one or more sensory stimulators, one or more sensors, and one or more physical computer processors, the method comprising:

• generating, with the one or more sensors, output signals conveying information related to brain activity of the subject;
• detecting, with the one or more physical computer processors, transitions in sleep state of the subject during the sleep session based on the output signals and baseline sleep state criteria;
• controlling, with the one or more physical computer processors, the one or more sensory stimulators to provide sensory stimulation to the subject with a timing based on the detected transitions in sleep state;
• subsequent to the sleep session, obtaining, with the one or more physical computer processors, reference indications of transitions in sleep state, the reference indications of transitions in sleep state being generated based on analysis of the output signals generated during the sleep session;
• comparing, with the one or more physical computer processors, the detected transitions in sleep state to the reference indications of transitions in sleep state;
• based on the comparison, adjusting, with the one or more physical computer processors, the baseline sleep state criteria to enhance correlation between detected transitions in sleep state during the sleep session using the baseline sleep state criteria and the reference indications of transitions in sleep state during the sleep session;
• and
• subsequent to adjustment of the baseline sleep state criteria, utilizing the adjusted baseline sleep state criteria to detect, with the one or more physical computer processors, transitions in sleep state of the subject for the purpose of controlling the one or more sensory stimulators.
