US20170340854

1. A system configured to adjust parameters of individual sensory stimuli provided to a subject, the system comprising: (4) (7)

a sensory stimulator configured to provide the individual sensory stimuli to the subject;

one or more sensors configured to generate output signals conveying information related to brain wave activity in the subject during a current sleep session; and

one or more physical computer processors configured by computer readable instructions to:

determine, based on the output signals, whether the subject is presently in slow wave sleep;

responsive to the subject being presently in slow wave sleep, control the sensory stimulator to provide the individual sensory stimuli to the subject, the individual sensory stimuli having a first parameter;

detect habituation of the subject to the individual sensory stimuli having the first parameter, habituation being detected based on the output signals for a period of time following the provision of the individual sensory stimuli having the first parameter; and

responsive to detection of habituation of the subject to the individual sensory stimuli having the first parameter, adjust the first parameter.

2. The system of claim 1, wherein the one or more physical computer processors are configured such that habituation is detected based on a derivative and/or the analysis of a trend of a slow wave activity versus time curve for the subject. (0)

3. The system of claim 1, wherein the one or more physical computer processors are configured such that adjusting the first parameter includes increasing a level of the first parameter and/or decreasing a level of the first parameter. (0)

4. The system of claim 1, wherein the one or more physical computer processors are configured such that the first parameter of the individual sensory stimuli is a duration of the individual sensory stimuli. (0)

5. The system of claim 1, wherein the one or more physical computer processors are configured to repeat the habituation detection and the adjustment of the first parameter of the individual sensory stimuli one or more times following provision of the individual sensory stimuli during a sleep session of the subject until slow wave sleep in the subject ceases. (0)

6. A method of operation of a parameter determination system, the system comprising a sensory stimulator, one or more sensors, and one or more physical computer processors, the method comprising: (4) (5)

generating output signals conveying information related to brain wave activity with the one or more sensors;

determining, based on the output signals, a slow wave sleep state with the one or more physical computer processors;

responsive to the determination, controlling the sensory stimulator, with the one or more physical computer processors, to provide the individual sensory stimuli, the individual sensory stimuli having a first parameter;

detecting, with the one or more physical computer processors, a state of habituation relative to the individual sensory stimuli having the first parameter, habituation being detected based on the output signals for a period of time following the provision of the individual sensory stimuli having the first parameter; and

responsive to the detection, adjusting, with the one or more physical computer processors, the first parameter.

7. The method of claim 6, further comprising detecting habituation of the individual sensory stimuli with the one or more physical computer processors based on a derivative of a slow wave activity versus time curve. (0)

8. The method of claim 6, wherein adjusting the first parameter with the one or more physical computer processors includes increasing a level of the first parameter and/or decreasing a level of the first parameter. (0)

9. The method of claim 6, wherein the first parameter of the individual sensory stimuli is a duration of the individual sensory stimuli. (0)

10. The method of claim 6, wherein habituation detection and adjustment of the first parameter of the individual sensory stimuli are repeated one or more times following provision of the individual sensory stimuli. (0)

11. A system configured to adjust parameters of individual sensory stimuli provided to a subject, the system comprising: (4) (6)

means for providing individual sensory stimuli to the subject;

means for generating output signals conveying information related to brain wave activity in the subject during a current sleep session;

means for determining, based on the output signals, whether the subject is presently in slow wave sleep;

means for, responsive to the subject being presently in slow wave sleep, controlling the sensory stimulator to provide the individual sensory stimuli to the subject, the individual sensory stimuli having a first parameter;

means for detecting habituation of the subject to the individual sensory stimuli having the first parameter, habituation being detected based on the output signals for a period of time following the provision of the individual sensory stimuli having the first parameter; and

means for, responsive to detection of habituation of the subject to the individual sensory stimuli having the first parameter, adjusting the first parameter.

12. The system of claim 11, wherein habituation is detected based on a derivative of a slow wave activity versus time curve for the subject. (0)

13. The system of claim 11, wherein adjusting the first parameter includes increasing a level of the first parameter and/or decreasing a level of the first parameter. (0)

14. The system of claim 11, wherein the first parameter of the individual sensory stimuli is a duration of the individual sensory stimuli. (0)

15. The system of claim 11, wherein habituation detection and adjustment of the first parameter of the individual sensory stimuli are repeated one or more times following provision of the individual sensory stimuli during a sleep session of the subject until slow wave sleep in the subject ceases.
