Abstract
This study examined characteristics of the brain networks related to upper limb grasp movements. EEG signal of 4 patients with chronic stroke were analyzed during different motor tasks. We compared the brain networks involved in the Active and Motor Imagery tasks by using the centrality and small-worldness (SW). There was a statistically significant difference between the centralities of two motor tasks in motor cortices of affected hemisphere in the high beta band (21 – 30 Hz). For SW, the Active task also decreased in the high beta band in contrast with the MI task. In this paper, we could support evidence that brain networks may different under the conditions of different motor tasks in both frequency and temporal domain.
