EEG Consciousness Measurement
CGI v4.1: Robust Cortical Consciousness Gradient Validated at Scale
From perfect ordering in controlled data to large-scale clinical confirmation—revealing dual pathways to consciousness.
CGI tracks sustained cortical integration (wake/NREM). REM's vivid dreams arise subcortically—consciousness beyond synchrony.
December 2025 breakthrough:
First strong IIT-aligned gradient with consumer-grade EEG. Extended validation (2025) on clinical data confirms robust wake-NREM decline, with REM highlighting subcortically-driven experience (pontine-hippocampal loops enabling consciousness despite desynchronization). CGT distinguishes cortical (sufficient for wake/NREM) from full-brain pathways.
Rally or Fade: A Breakthrough in Consciousness Measurement
Validated at Macro-Scale (Minutes to Hours)
Our EEG-based consciousness measurement framework has been validated at session-level timescales, demonstrating:
- Large, robust effects (effect sizes 0.5 to 1.6)
- High detection sensitivity (76% of subjects)
- Two distinct consciousness response patterns
- Predictive baseline assessment
What happens to your consciousness when you push through sustained mental effort? Do you rally and adapt, or do you fade and decline?
Rally or Fade: Discovering Two Paths of Consciousness Under Load
Technical Specifications:
