In all spheres of activity, a person constantly tries to control its own manual motor skills and to change it according to his or her needs. Therefore, studying of the processes related to both motor responses: activation and inhibition is especially interesting (modified version of the Go-No Go paradigm, the so-called Stop-Signal task, Logan, 1984) as well as appraisal of the following, alternative response after stopping by examinees doing already started motor action (Go-Stop-Change paradigm, Verbruggen et al., 2008; Boecker et al., 2013). It is worth to emphasize that there is still a real shortage of researches when using the paradigm of Go-Stop-Change. The question of what cerebral mechanisms (identical or dissimilar) provide inhibition of the experimental Stop-Signal and Stop-Change paradigms remains open. To analyze the respective manifestations, we used the technique of recording of event-related EEG synchronization/ desynchronization (Neuper et al., 2006; Pfurtscheller, 2001), establishing spatial localization of cortical activity sources under this conditions. We expect that application of such techniques will help us to find concrete cortical indices (markers) of the time course of motor programming. The use of such EEG markers may open some prospects for the qualitative improvement of early diagnostics of cortical dysfunctions. popup.nrat_date 2024-12-10 Close
