Power spectrum of electroencephalogram: Mistakes and Practical Application
In this lecture, the state of the practical use of spectral analysis of EEG is analyzed in detail. The author focuses on the reasons for the slow introduction of spectral analysis into everyday practice and identifies ways to overcome this deficiency. The reason for the need to master this useful analysis technique has been substantiated. The algorithm for performing spectral analysis of EEG in practice, both at the stage of processing and at the stage of data interpretation, is presented in detail. In the lecture, the author outlined the features of the options for the spatial organization of the alpha rhythm and their relationship with the characteristics of the human psyche. One of the reasons that hinders the use of EEG spectral analysis in practice is the lag of the software of electroencephalographic computer systems of leading manufacturers from modern requirements of the time.
