HIRREM Developmental Study

HIRREM is a noninvasive, closed-loop, allostatic, acoustic stimulation neuro-technology to facilitate recipient-unique relaxation, auto-calibration, and self-optimization of cortical neural oscillations by reflecting auditory tones in near real time. After an initial HIRREM assessment, evaluating patterns of brain electrical rhythms, subjects get a series of 90-120 minute HIRREM sessions, including 5 to 9 individualized protocols. A protocol is a combination of sensor montage and specific software design, during which dominant brain frequencies, recorded at high spectral resolutions, are translated to audible tones, and reflected back via earphones with as little as 8 milliseconds delay. Protocols are received sitting or reclining in a chair, some with eyes open, others eyes closed.
