Abstract
A neurofeedback enhancement system incorporating monaural audio beats, optical LED photic entrainment, and nIR LED photobiomodulation entrainment components to augment the EEG neurofeedback process. The frequency of operation for the entrainment modalities is set based on the dominant energy frequency attributes of the subjects EEG. The intensity of the entrainment modalities is dynamically modulated in response to real time analysis of targeted EEG features, and all modalities are synchronized in time.
Claims17
A method, comprising:
- generating, via a processor, a first signal having a first frequency;
- generating, via the processor, a second signal having a second frequency, a difference between the first frequency and the second frequency being substantially equal to a dominant electroencephalogram (EEG) frequency derived from a subject;
- generating, via the processor, a third signal based on the first signal and the second signal;
- rectifying, via the processor, the third signal to generate a rectified signal;
- filtering, via the processor, the rectified signal to generate a filtered signal;
- identifying, via the processor, peaks of the filtered signal having a value greater than a predetermined threshold value;
- generating, via the processor and based on the filtered signal and the peaks of the filtered signal, a fourth signal based on the third signal;
- causing, via the processor, audio generated based on the third signal to be output;
- and
- causing, via the processor and while outputting the audio representing the third signal, a plurality of light emitting diodes (LEDs) included at a headset to activate and deactivate based on the fourth signal.
An apparatus, comprising:
- a memory;
- and
- a processor operatively coupled to the memory, the processor configured to:
- send an audio signal to a speaker to cause the speaker to output audio based on the audio signal, the audio signal generated based on combining a first signal having a first frequency and a second signal having a second frequency, a difference between the first frequency and the second frequency being substantially equal to a dominant electroencephalogram (EEG) frequency derived from a subject;
- and
- send a light emitting diode (LED) drive signal to a plurality of LEDs to cause the plurality of LEDs to activate based on the LED drive signal, the LED drive signal generated by
- rectifying the audio signal to generate a rectified signal,
- filtering the rectified signal to generate a filtered signal,
- identifying peaks of the filtered signal having a value greater than a predetermined threshold value, and
- generating the LED drive signal based on the filtered signal and the peaks of the filtered signal.
A non-transitory processor-readable medium storing code comprising instructions to be executed by one or more processors, the instructions causing the one or more processors to:
- send an audio signal to a speaker to cause the speaker to output audio based on the audio signal, the audio signal generated based on a first signal having a first frequency and a second signal having a second frequency, a difference between the first frequency and the second frequency being substantially equal to a dominant electroencephalogram (EEG) frequency derived from a subject;
- rectify the audio signal to generate a rectified signal;
- filter the rectified signal to generate a filtered signal;
- identify peaks of the filtered signal having a value greater than a predetermined threshold value;
- generate a light emitting diode (LED) drive signal based on the filtered signal and the peaks of the filtered signal;
- and
- send the LED drive signal to a plurality of LEDs to cause the plurality of LEDs to activate based on the LED drive signal, the LED drive signal generated based on the audio signal.
