What do the sensors do, and how does it work?

The headset uses two types of sensors:

• Three midline EEG electrodes reading brainwave activity from delta through the third harmonic of gamma (1 Hz to 120 Hz) with lab-grade precision.
• A pulse oximeter on the left earcup reading heart rate, heart rate variability, and heart rate coherence.
• 
  

These readings tell the app about your physiological state in real time. The app processes the signal into Program-specific feedback: sound through the headphones, and sometimes visuals on the app screen. The sensors also inform the transcranial photobiomodulation (tPBM) light stimulation, matching its pulsing frequency to your own brainwaves.
