Abstract:
1. A method of monitoring neurological function, comprising: acquiring electroencephalogram signals from a subject; and processing and analyzing data from the electroencephalogram signals using at least one entropy method selected from the group consisting of: Shannon entropy, Tsallis entropy, Renyi entropy, time dependent entropy, time multi-resolution dependent entropy, relative time dependent entropy, relative time multi-resolution dependent entropy, residual time dependent entropy, residual time multi-resolution dependent entropy, subband wavelet entropy, multi-resolution wavelet entropy, relative subband wavelet entropy, relative multi-resolution wavelet entropy, residual subband wavelet entropy, and residual multi-resolution wavelet entropy; wherein the processing and analyzing data includes analyzing at least one electroencephalogram waveform segment, wherein the at least one electroencephalogram waveform segment comprises a plurality of data points from the electroencephalogram signal; and wherein the processing and analyzing data further comprises calculating the maximum and minimum amplitude value of the data points from the at least one electroencephalogram waveform segment and determining an amplitude domain with upper and lower amplitude boundaries based on statistical analysis and processing of the maximum and minimum amplitude values of the at least one electroencephalogram waveform segment.
