Abstract

Systems and methods for brain stimulation.

Claims

1. A stimulation system for stimulating a subject, the system comprising:

a learning component and a consolidation component, wherein the learning component comprises;

auditory stimulation apparatus for delivering one or more selected auditory stimulations to the subject; and

one or more self-actuation inputs operably coupled to the auditory stimulation apparatus for self-actuation by the subject to deliver at least one selected auditory stimulation of the one or more selected auditory stimulations to the subject;

and wherein the consolidation component comprises;

monitoring apparatus for monitoring the sleep state of a subject, wherein the monitoring apparatus optionally comprises one or more electrodes;

auditory stimulation apparatus for delivering one or more selected auditory stimulations to the subject; and

a controller operably coupled to the monitoring apparatus to receive input regarding the sleep state of the subject from the monitoring apparatus and operably coupled to the auditory stimulation apparatus to operate the auditory stimulation apparatus, wherein the controller utilizes the input from the monitoring apparatus to determine when the subject is in one or more selected sleep states, and further wherein the controller operates the auditory stimulation apparatus to deliver at least one selected auditory stimulation of the one or more selected auditory stimulations previously delivered by the learning component to the subject during at least one selected sleep state of the one or more selected sleep states.

2. The stimulation system of claim 1, wherein the learning component and the consolidation component are components of a single integral unit.

3. The stimulation system of claim 1, wherein the learning component is a component of a first unit, wherein the consolidation component is a component of a second unit, and wherein the second unit is separate from the first unit.

4. The system of claim 1, wherein the monitoring apparatus comprises electroencephalography apparatus.

7. The system of claim 1, wherein the monitoring apparatus comprises electromyography apparatus.

10. The system of claim 1, wherein the monitoring apparatus comprises electrooculography apparatus.

13. The system of claim 1, wherein system further comprises a self-contained patch and adhesive to attach the self-contained patch to the subject, wherein the monitoring apparatus, the auditory stimulation apparatus, and the controller are located on the self-contained patch.

14. The system of claim 1, wherein the auditory stimulation apparatus comprises:

memory for storing one or more selected auditory stimulations; and

one or more output devices, wherein the one or more output devices deliver the one or more selected auditory stimulations.

15. The system of claim 1, wherein the system further comprises a configuration apparatus to configure the system, wherein the configuration apparatus comprises:

processing apparatus;

a first input interface coupled to the processing apparatus to receive input from the subject; and

an input/output interface coupled to the processing apparatus to transmit data to the controller of the stimulation system.

21. A method of stimulating a subject'"'"'s brain, the method comprising:

providing auditory stimulation apparatus for delivering a plurality of different auditory stimulations to a subject;

providing monitoring apparatus to monitor the state of the subject;

positioning the auditory stimulation apparatus where the subject can hear the auditory stimulations;

delivering selected auditory stimulations from the plurality auditory stimulations from the auditory stimulation apparatus to the subject during one or more first periods when the subject is awake; and

delivering the selected auditory stimulations from the plurality of auditory stimulations from the auditory stimulation apparatus to the subject during one or more second periods when the subject is asleep.

22. The method of claim 21, wherein each first period of the one or more first periods has a finite duration during which the subject is learning a specific task, and wherein each first period of the one or more first periods corresponds to a different specific task.

23. The method of claim 21, wherein a different selected auditory stimulation of the plurality of different auditory stimulations is delivered to the subject during each first period of the one or more first periods, and further wherein each different selected auditory stimulation that was delivered to the subject during each first period of the one or more first periods is delivered to the subject during each second period of the one or more second periods.

39. The method of claim 24 further comprising:

selecting each second period of the one or more second periods to correspond to a period when the electrical activity of the subject'"'"'s brain is undergoing sleep spindles.

41. The method of claim 24, wherein electrical activity in the subject'"'"'s brain indicative of stage II sleep immediately preceding rapid eye movement occurs during each second period of the one or more second periods.

42. The method of claim 24 further comprising:

selecting each second period of the one or more second periods to correspond to a period when the electrical activity of the subject'"'"'s brain indicates that the subject is undergoing stage II sleep immediately preceding rapid eye movement.

44. The method of claim 21, wherein rapid eye movement of the subject occurs during each second period of the one or more second periods.
