Searching and using of time intervals of brain activity in a problem of solving process by estimation of negentropy of EEG

In the analysis of a brain activity it is actual to find time intervals that represents only brain activity. We have developed a new software instrument that helps to search and visualize such intervals. The base assumption of this work is that distribution of the amplitude of signal that represents brain activity is significantly different from a Gaussian distribution. So we use negentropy as an indicator of intervals of brain dynamics. As a result, the developed instrument helps to analyze EEG information visually and make further mathematical calculations with the results.
