Scaling of the Background Brain Dynamics and Alpha Rhythm

The scaling property of the brain dynamics is studied based on the zero-crossing of the local electroencephalographic (EEG) recording taken from healthy young adults in eyes closed and eyes open. Evidence of coupling between the EEG fractal dynamics and the $α$ rhythm is presented. An organization principle that governs this coupling relationship is proposed. In the $α$ dominant brain state, a possible interpretation using the self-organized criticality similar to the punctuated equilibrium is discussed.

Discrete Scale Invariance in the Cascade Heart Rate Variability Of Healthy Humans

Evidence of discrete scale invariance (DSI) in daytime healthy heart rate variability (HRV) is presented based on the log-periodic power law scaling of the heart beat interval increment. Our analysis suggests multiple DSI groups and a dynamic cascading process. A cascade model is presented to simulate such a property.
