**11. Conclusion**

The study of the functional activity of the brain remains the most important problem in clinical neurophysiology. But for its solution, it requires the combined efforts of specialists from different areas of neuroscience and is unthinkable without the improvement of methods that make it possible to fix, localize, and understand the processes occurring in the nervous tissue.

The EEG method developed at the beginning of the twentieth century still retains its relevance in the clinic of neurological diseases. The main and most demanded advantage of the EEG method is the possibility of direct study of the bioelectrical activity of brain structures, which makes it possible to study processes with rapid dynamics occurring in brain structures.

Nevertheless, methodological approaches to the analysis of electroencephalograms need a thorough revision and the formation of a unified methodological approach to the implementation of research, especially with the active introduction of multichannel systems combined with computer signal processing into clinical practice, which in the future can change many ideas about the pathogenesis of various neurological diseases and suggest the most rational approaches to their therapy and rehabilitation.
