Quantifying consciousness through intrinsic probability density function.
Biological Psychology September 1, 2025 Norden E Huang, Wei-Shuai Yuan, Albert C Yang et al.
Consciousness remains a multifaceted phenomenon that is difficult to be measured by traditional quantification methods. Here we propose the intrinsic probability density function (iPDF) as a quantitative method to evaluate the dynamic inter-cortical interactions that underlie conscious states. First, the method utilizes empirical mode decomposition to derive intrinsic mode functions (IMFs) from...
