Mechanism of Action
Binaural auditory stimulation exploits the frequency-following response (FFR) of the auditory cortex. When two tones of slightly different frequency are presented dichotically (one per ear), the superior olivary complex generates a perceptual "beat" at the difference frequency. Sustained exposure (8-12 min) induces cortical entrainment, shifting dominant EEG power toward the target band.
Carrier (L): 200 Hz
Carrier (R): 200 + f Hz
Perceived beat: f Hz
Onset of entrainment: ~8 min
Optimal session: 25-45 min
Protocol Recommendations
Theta Divergent thinking, ideation, writing. Use early morning or post-exercise when cortisol is elevated.
Alpha Sustained attention, reading, learning. Optimal mid-morning (9-11 AM) when adenosine is low.
Beta Analytical work, coding, data processing. Effective during peak alertness windows.
Gamma Cross-modal integration, complex synthesis. Reserve for high-stakes cognitive tasks.
Key: Headphones required. Over-ear recommended for seal quality. Begin binaural 2-3 min before starting focused work to allow entrainment onset.
