During the last few decades, the work of neurocognitive issues within the frame of brain imaging techniques has been of considerable interest. Our approach, in this paper, concerns with the evaluation of EEG signal analysis using several pattern recognition methods. Furthermore, a comparing analysis to linear and nonlinear pattern recognition for enhanced efficiency of fuzzy logic systems has been carried out. A description of fuzzy logic principles, fuzzy logic systems and brain waves activity analysis within the frame of fuzzy logic methods is also given. Authors’ future directions are to verify and enhance the theoretical and empirical findings concerning the fuzzy logic systems accuracy.
