Applications of Higuchi's fractal dimension in the analysis of biological signals

Significant contribution to understanding of complex biological systems emerged from application of fractal analysis. This paper presents a fractal analysis as one of many mathematical methods in the analysis of biological signals. Higuchi's fractal dimension is used in stationary and quasi-stationary bio-signals (EEG, ECoG) analysis and appropriately modified in the analysis of the bimodal pattern of neuronal activity as non-stationary signals.
