Sleep Research with Cerebra Sleep System

New Breakthroughs Using Cerebra Sleep System

A growing number of researchers are uncovering new breakthroughs using Cerebra Sleep System, the most advanced self-applied, in-home polysomnography (PSG) with clinical quality data collection and novel EEG metrics such as Odds Ratio Product (ORP) – a highly validated measure of sleep depth.

Cerebra Sleep System is a powerful scientific sleep diagnostic technology enabling:

  • natural home environment study of patient’s sleep depth
  • informed diagnosis of sleep disorders and ultimately personalized treatment
  • enhanced diagnosis of disease, cognitive impairment, injury or loss of executive function
  • reduction of human bias and increased consistency on large data sets with consistent autoscoring
  • elimination of geographic barriers with remote access to a cloud platform to upload data, manage equipment, schedule sleep studies, analyze study results, produce patient reports, and more

Lab based research is performed in an unrealistic environment. Lab research is expensive and prone to small sample sizes.

Cerebra Sleep System as a self-applied, in-home PSG allows for the following:

  • more refined measure of sleep depth
  • reduced costs and expenses
  • increased sample sizes
  • decreased wait times

ORP and Sleep Stages

When compared to Conventional Sleep Staging, ORP provides a more detailed and continuous measure of sleep. This allows for higher resolution and shows the discrepancy of sleep depth within Stage Non-REM 2. This can also be shown in wakefulness; different levels of vigilance potentially identify people with poor sleep quality even though they have a similar histogram.

A head-to-head comparison to delta power concluded ORP is more discriminating among sleep stages, more sensitive to sleep restriction, and more closely associated with arousability.[1]”
Delta power identifies deep sleep, but doesn’t tell anything about sleep depth when not in Stage Non-REM 3. (Younes et al., 2020)
