Classification of Different Brain Dynamics Associated to Different Cognitive Modalities: Towards an Understanding of Self-willed Generated Cognitive States

Abstract

In recent years the Planckian distribution was introduced by [1] to characterize biophysical oscillatory processes that generate distributions similar to the Planck radiation equation, Planck’s law [2, 3]. In the Planck radiation equation, temperature (T) plays a fundamental role in shaping the spectrum distribution. Here we apply the Planckian distribution equation to model different brain states presumably associated to different cognitive states, where we propose that the generalized parameters of the Planckian distribution equation could act as predictors of the distribution shape and the brain states analogous to the role of temperature (T) in the Planck equation. In our case we propose that the parameters could be associated to the power of will, attentional focus or commitment to a way of being with certain associated brain dynamics and we show the different distributions associated to brain data collected for twenty (20) participants, in meditation/relaxation or an engaged audio-visual task. We conclude that even though brain dynamics as described by Ji’s Planckian distribution (JPD) in fMRI studies have been successful when measuring EEG signals in humans, the JPD shows to be limited in characterizing the experimental power spectrum recorded for multiple participants in the two (2) modalities analyzed. However, the Gaussian and Lorentzian distributions do fit the data and significantly succeed in characterizing the data, even in the case of bi- or multi-modality, when combining two (2) or more Gaussian or Lorentzian distributions.
