Entropy changes in brain function

The traditional way of analyzing brain electrical activity, on the basis of electroencephalography (EEG) records, relies mainly on visual inspection and years of training.

EEG Epilepsy ERP Signal entropy Wavelet analysis analysis article brain function electroencephalography entropy epilepsy event related potential human signal processing spike wave Acoustic Stimulation Adult Algorithms Brain Child Data Interpretation, Statistical Electroencephalography Entropy Epilepsy Epilepsy, Absence Evoked Potentials Evoked Potentials, Auditory Evoked Potentials, Visual Humans The traditional way of analyzing brain electrical activity, on the basis of electroencephalography (EEG) records, relies mainly on visual inspection and years of training. Although it is quite useful, of course, one has to acknowledge its subjective nature that hardly allows for a systematic protocol. In the present work quantifiers based on information theory and wavelet transform are reviewed.

The "normalized total wavelet entropy" carries information about the degree of order-disorder associated with a multi-frequency signal response.

description	The traditional way of analyzing brain electrical activity, on the basis of electroencephalography (EEG) records, relies mainly on visual inspection and years of training.
