Abstract

Methods and devices are provided for monitoring and manipulating a person'"'"'s brainwaves to achieve a desired mental state. A method of improving a student'"'"'s test-taking ability includes analyzing EEG data to determine a student'"'"'s focus level during an exam and providing a suggestion to the student for improving the student'"'"'s focus level. A method of manipulating brain activity includes measuring a listener'"'"'s brainwave frequency and providing binaural beats to the listener to guide the listener to a desired mental state. The binaural beats may be incorporated into music in such a way that they may not be distinguished over the music. A portable apparatus includes EEG electrodes connected to earphones with malleable wire that facilitates preferential placement and stability on a user'"'"'s scalp.

Claims

1. A method of improving a student'"'"'s test-taking ability, the method comprising the steps of:

receiving EEG data from the student while the student is taking an exam;

analyzing the EEG data to determine a focus level of the student during the exam;

correlating the focus level of the student with a score the student received on the exam;

receiving lifestyle data from the student, the lifestyle data describing an activity the student performed prior to the exam; and

providing the student with feedback comprising at least one suggestion for improving the student'"'"'s focus level.

2. The method of claim 1, wherein the exam is a practice exam for an SAT exam, an AP exam, an ACT exam, a GRE exam, an MCAT exam, or an LSAT exam.

3. The method of claim 1, wherein the focus level is correlated with a score the student received on a question from the exam.

4. The method of claim 1, wherein the focus level is correlated with a difficulty level of a question from the exam.

5. The method of claim 1, wherein the activity comprises at least one member selected from the group consisting of sleeping, eating, resting, and exercising.

6. A method of manipulating brain activity, the method comprising the steps of:

(i) filling a buffer with a portion of a song to be played to a listener;

(ii) determining a characteristic frequency f_c of the portion of the song;

(iii) measuring a brainwave frequency of the listener;

(iv) comparing the brainwave frequency of the listener with a target frequency associated with a desired listener state;

(v) determining a binaural beat frequency based on the brainwave frequency of the listener and the target frequency, wherein the binaural beat frequency is determined to guide the listener to the desired listener state;

(vi) playing the portion of the song for the listener;

(vii) providing a first frequency f₁ to a first ear of the listener; and

(viii) providing a second frequency f₂ to a second ear of the listener, wherein a difference between the first frequency f₁ and the second frequency f₂ is equal to the binaural beat frequency, and wherein an average of the first frequency f₁ and the second frequency f₂ is substantially equal to the characteristic frequency f_c of the portion of the song.

7. The method of claim 6, wherein the characteristic frequency f_c corresponds to a musical tone within the portion of the song.

8. The method of claim 6, wherein the binaural beat frequency follows a stepwise function.

9. The method of claim 6, wherein filling the buffer comprises storing the portion of the song in the buffer before the portion of the song is played for the listener.

10. The method of claim 6, further comprising the step of receiving the song from a music streaming service.

11. The method of claim 6, further comprising the step of receiving the song from the listener.

12. The method of claim 6, wherein the characteristic frequency f_c, the first frequency f₁, and the second frequency f₂ are time-dependent.

13. The method of claim 6, wherein the first frequency f₁ and the second frequency f₂ change in response to a change in the characteristic frequency f_c.

14. The method of claim 6, further comprising repeating steps (i) through (viii) for a subsequent portion of the song.

15. A portable apparatus for manipulating brain activity, the apparatus comprising:

a set of earphones for delivering binaural beats to a user;

an EEG electrode for detecting a brainwave of the user, the EEG electrode connected to the set of earphones with malleable wire that facilitates preferential placement and stability on the user'"'"'s scalp; and

a brainwave detection device in electrical communication with the EEG electrode, the brainwave detection device configured to;

(i) measure a brainwave frequency of the user;

(ii) compare the brainwave frequency of the listener with a target frequency associated with a desired mental state;

(iii) determine a binaural beat frequency based on the brainwave frequency of the user and the target frequency; and

(iv) provide the binaural beat frequency to the listener, wherein the binaural beat frequency is determined to guide the use to the desired mental state.

16. The apparatus of claim 15, comprising a music player in communication with the brainwave detection device.

17. The apparatus of claim 15, wherein the earphones comprise earbuds.

18. The apparatus of claim 15, wherein the EEG electrode is a dry sensor EEG electrode.

19. The apparatus of claim 15, comprising a grounding electrode in electrical communication with the EEG electrode.
