CRI has developed an advanced, single-channel, EEG-based wake/sleep detection system (patented and patents pending). This system operates on the differential-mastoid EEG channel to determine the sleep state (i.e. awake or asleep) every 30 seconds throughout the night in real time.

Insomnia Treatment

---

CRI has developed a novel treatment device for chronic insomnia utilizing CRI's advanced single-channel EEG-based wake/sleep detection technology. This system enables improved in-home delivery of cognitive behavioral therapy. Click HERE to read the laboratory testing overview.

CRI initiated an in-home study of the insomnia treatment prototype devices. Click HERE to read about the in-home pilot study.

Sleep Apnea

---

Analysis of one-hour nap data from early CRI human performance testing provides an indication that the sleep fragmentation / micro-arousals associated with sleep apnea may be detectable using algorithms operating on High Frequency EEG signals.
