A new software system is developed. It allows to identify time intervals that represent «inclusion» and «cessation» of a brain in a problem solving process. The base assumption of that work is that distribution of the amplitude of signal that represents brain activity is significantly different from a Gaussian distribution. Since defined time intervals represents brain dynamics, the developed system allows a more accurate analysis of brain activity and event-related spectral perturbations.

Key Words
electroencephalography, negentropy, independent component analysis
