Traditional Sleep EEG Is Hard to Scale

  • Complex setups reduce compliance

  • Technician involvement limits deployment

  • Lab environments introduce first night effect

  • Longitudinal studies become costly and operationally difficult

  • Fixed sensor configurations add unnecessary complexity

One Night Tells a Story. Multiple Nights Reveal a Pattern.

 

Traditional sleep studies often capture a single night in an unfamiliar environment. Sleep, however, varies night to night.

CGX enables repeatable sleep EEG recordings across days, weeks, and entire studies, helping researchers observe trends, variability, and intervention effects.

The CGX Approach

CGX focuses on the core signal used in sleep staging: EEG.

Instead of forcing every workflow into a full lab-style setup, CGX enables modular sleep monitoring built around wearable EEG, automated sleep staging, physiology, and circadian context.

 

Why This Matters

  • Self-applied wearable sleep EEG

  • No technician required

  • Designed for at-home deployment

  • Modular physiology and circadian context

  • Automated sleep staging

  • Longitudinal monitoring at scale

Scientifically Grounded Sleep Staging

EZScore applies machine-learning sleep staging to wearable forehead EEG using the validated ezscore-f framework.

Validated against expert-scored recordings from the OpenNeuro Forehead EEG dataset:

​

  • 19 subjects

  • 19,547 valid epochs

  • Strongest agreement in N2, N3, and REM sleep

  • Explicit artifact handling for increased transparency

CGX Flowpoint 

Central Hub for Sleep EEG Workflows

​

Flowpoint is the central hub for sleep EEG acquisition, visualization, export, reporting, and integration.

​

Record data, review recordings, generate reports, and connect sleep EEG with third-party tools through a single workflow.

​

All data acquisition, analysis, report generation, and raw data export run locally on your computer. Sleep recordings are not uploaded for processing.
