The purpose of this work was to analyze the spatial and temporal dynamics of EEG parameters during performance of tasks with dominance of mental and sensory attention. In addition, an attempt to identify differences in dynamics of EEG parameters in such close mentally oriented tasks as a productive and reproductive imagination was made. EEG wavelet spectrum and phase coherence (relationships between EEG-channels) were studied for \(\theta \), \(\alpha \) and \(\beta \) frequency ranges of EEG. Analysis of the data showed significant numerous differences of EEG wavelet spectrum and phase coherence between tasks with the dominance of mental and sensory attention and also between such close mental states as productive and reproductive imagination. Time dynamics of EEG differences, obtained in different frequency ranges, allows us to trace which processes were consequentially involved in realization of investigated states on different time intervals and provide new information for understanding of brain mechanisms of these states. |
