Topicality. A core of any activity, including sports, is the process of new functional programs that provide adaptation to this activity. The effectiveness of these functional programs, on the one hand, depends on the innate neurodynamic properties of the body, and on the other, on the characteristics of the training process. The study of athletes` neurophysiological processes is important for sports selection and is the main basis for managing the athletes` trainings for the competitive period. Achieving high results in sports requires not only excellent physical qualities, but also special features of perceptual functions, in particular in those sports that require fast response in non-standard game conditions, and choosing the right decision during set goal. The Purpose of the Research is to study and analyze the features of the localization of evoked cortical activity in athletes and football players. In accordance with the purpose, the following tasks were set: to analyze the scientific and methodological literature on the issue of study the evoked potentials of athletes; to study and analyze the spatial localization of evoked cortical activity in athletes and football players. Research Methods. The electroencephalography (EEG), Independent component analysis (ICA) and mathematical methods of statistics were used in the research. As a Result of the research in both groups of athletes revealed sources of induced activity in the anterior associative parts of the cerebral cortex. In football players, during the perception and processing of a significant object, sources of activity in the parietal lobe have been identified, and in athletes – frontal and temporal cortices. Others were characterized by sources of induced activity in the thalamus and parahypocampus. Conclusions. The frontal lobe is involved in assessing the semantic meaning of the stimulus. The thalamus, through its thalamocortical and cortical thalamic connections, affects the cerebral cortex and the cortex affects it. The positive influence of sports activities on the processes of perception and processing of significant information in the cerebral cortex has been established.
