Abstract

Recent studies report an increase of synchrony between different brain areas and bands during the development of mental tasks. Furthermore, there is a high interest in the study of gamma band because the literature reports considerable evidence that neural oscillations and synchronization in high frequency and large-scale integration [1]. The analysis of synchrony (Phase Locking Value) for the analysis of gamma band was applied for the discrimination of cognitive tasks and their performances were compared with the implementation of Wavelet transform. The results showed that PLV analysis reported a difference of 9 pairs of mental tasks in comparison with the Wavelets analysis that reported a difference of 5 mental tasks. Moreover, the approach with PLV reported a smaller processing time; the analysis of synchronous brain thus shows encouraging results as a tool for discriminating cognitive tasks.
