1. A device, comprising: (6) (5)

a substrate having a first side and a second side, the second side being opposite the first side;

a plurality of electrodes positioned along the first side of the substrate;

a stimulator coupled to and positioned on the second side of the substrate;

at least one lead coupling the plurality of electrodes to the stimulator; and

a band positioned along a second side of the substrate and about each of the plurality of electrodes.

2. The device of claim 1, wherein the substrate is flexible to permit the substrate to attain a curved shape, and the substrate includes an adhesive. (0)

3. The device of claim 1, wherein the plurality of electrodes includes four electrodes aligned on an axis of the substrate, and the plurality of leads includes four leads, each of the four leads corresponding to one of the four electrodes. (0)

4. The device of claim 1, wherein the electrodes and the leads are printed on the substrate. (0)

5. The device of claim 1, wherein the band includes a flexible fabric that covers an entirety of the substrate. (0)

6. The device of claim 1, wherein the substrate includes a first coupling mechanism having a shape corresponding to a shape of a first coupling feature of the stimulator, and the band includes a second coupling mechanism having a shape corresponding to a shape of a second coupling feature of the stimulator. (1) (0)

8. The device of claim 1, further including a sensor located on at least one of the plurality of electrodes for measuring a physiological parameter of a subject. (0)

9. A method, including: (6) (5)

positioning a plurality of electrodes on a forehead of a subject;

delivering transcranial stimulation to the subject via the plurality of electrodes at a first frequency;

ceasing delivery of transcranial stimulation at the first frequency;

monitoring brain activity of the subject at least after ceasing delivery of transcranial stimulation at the first frequency; and

delivering transcranial stimulation to the subject via the plurality of electrodes at a second frequency, different than the first frequency.

10. The method of claim 9, wherein monitoring brain activity includes sensing a frequency of electrical activity of the subject's brain via a sensor and the second frequency corresponds to a frequency of electrical activity sensed via the sensor. (0)

11. The method of claim 9, wherein monitoring brain activity includes determining whether a portion of the brain associated with dreaming has been stimulated to a predetermined level. (0)

12. The method of claim 9, further including receiving feedback from the subject as to whether or not the subject had a lucid dream, and wherein the sensed frequency is based, at least in part, on the feedback. (0)

13. The method of claim 9, wherein delivering transcranial stimulation to the subject via the plurality of electrodes at at least one of the first frequency or the second frequency includes delivering a stimulation waveform including two or more frequencies. (0)

14. The method of claim 9, further including delivering transcranial stimulation via the plurality of electrodes at the first frequency at pre-programmed intervals, and wherein the first frequency is between 20 Hz and 60 Hz. (0)

15. The method of claim 9, further including determining whether the subject has entered a Rapid Eye Movement (REM) sleep period, prior to delivering transcranial stimulation at the first frequency. (0)

16. A method, including: (4) (5)

positioning a plurality of electrodes on a head of a subject;

delivering transcranial stimulation to the subject via the plurality of electrodes at a first frequency;

ceasing delivery of transcranial stimulation at the first frequency;

determining a change of frequency of brain activity of the subject from the first frequency towards a frequency exhibited by a brain of the subject after ceasing delivery of transcranial stimulation at the first frequency; and

delivering transcranial stimulation to the subject via the plurality of electrodes at the frequency exhibited by the brain of the subject after ceasing delivery of transcranial stimulation at the first frequency.

17. The method of claim 16, further including delivering visual or audio content relating to a topic prior to delivering transcranial stimulation at the first frequency or the frequency exhibited by the brain of the subject after ceasing delivery of transcranial stimulation at the first frequency. (0)

18. The method of claim 16, delivering transcranial stimulation via the plurality of electrodes at the first frequency at pre-programmed intervals, and wherein the first frequency is between 25 Hz and 40 Hz. (0)

19. The method of claim 16, further including determining whether the subject has entered a Rapid Eye Movement (REM) sleep period, prior to delivering transcranial stimulation at the first frequency. (0)

20. The method of claim 16, further including: (0) (2)

21. A method, including: (0) (4)

positioning a plurality of electrodes on a forehead of a subject;

delivering transcranial stimulation to the subject via the plurality of electrodes at a first frequency; and

delivering transcranial stimulation to the subject via the plurality of electrodes at a second frequency, different than the first frequency;

wherein delivering transcranial stimulation to the subject via the plurality of the electrodes at a first frequency is performed simultaneously with delivering transcranial stimulation to the subject via the plurality of the electrodes at the second frequency.
