Abstract
En 中文
• Introduces iPDF to quantify consciousness via EEG. • Uses empirical mode decomposition to generate scale-dependent probability density functions • Distinguishes conscious from unconscious states by iPDF. • Identifies neural interactions or modulations via super-Gaussian vs. Gaussian EEG profiles. • Achieves 81 % accuracy in dementia classification.
