This study identifies electrophysiological correlates of lucid dreaming using EEG data from multiple labs, finding source-level changes in gamma1 and alpha power.

This paper introduces fractal cycles as a new definition of sleep cycles based on fractal neural activity, showing correlations with classical cycles and differences across age groups and depression states.

This study differentiates phasic and tonic REM sleep states using aperiodic neural activity slopes, showing phasic states have steeper low-band and flatter high-band slopes, and EM amplitudes correlate with these slopes.

This study tests a combined sensory and cognitive approach to induce lucid dreaming, finding higher rates of signal-verified lucid dreams with sensory cues compared to sham conditions.

The paper validates a wearable PSG system, ZMax, comparing its sleep scoring and metrics to standard PSG, finding moderate to substantial agreement with human scorers.
