- Primary Outcome Measures
Name Time Method The primary goal of this study is to measure the different changes in the lateralization of ERD (event-related desynchronization) as a prominent neurophysiological correlate of motor perception. The ERD is calculated from the recorded EEG data. <br>Data of the sample to be collected (elderly neurologically healthy persons) and data of an existing sample (young neurologically healthy persons) whose data set already exists for the same task are compared. The percentage change in ERD is the main criterion of the study. The underlying scale of the ERD is always given in µV<br>In the group of stroke patients in the chronic stage, is it of primary interest whether they are subjectively able to imagine the complex visuomotor task?<br><br>
- Secondary Outcome Measures
Name Time Method - Are there objectively detectable deviations of the patient's imagination in comparison to healthy subjects of the same age for the complex visuomotor task, e.g. the duration of the idea of movement or the duration of ERD?<br>- How does ERD change in the course of the experiment in the individual groups?
