Multifractal detrended fluctuation analysis used to analyse EEG signals originating from different lobes of brain

Abstract

The electrical activity of human brain when subjected to puzzle stimulus & musical stimuli is recorded as EEG. Non-linear analysis method MFDFA was used to analyze long-lasting effect of music on rest state of brain. Multifractal width and Hurst exponent are used as an indicator of multifractality in our analysis. EEG data was also shuffled to find out the origin of multifractality(i.e. whether due to long range correlation, broad probability density or both).
