Abstract

Based on the results of the EEG experiment in the process of human motor execution, we performed in this paper a source-level analysis of brain activity during the motor initiation phase for two age groups: young and elderly adults. In the theta frequency band, we discovered stronger activation of the contralateral area of the primary motor cortex (Postcentral L and Precentral L zones) for elderly subjects compared to young ones in the right (dominant) hand movements. We discuss the correlation of the obtained source-level results with the known age-related slowing down in the motor initiation before the dominant hand movements. The obtained results are essential for explaining age-related changes in behavioral characteristics, such as reaction time, the accuracy of motor performance, etc.
