Abstract

The exploration of neural activity patterns in motor imagery offers a new way of thinking for improving motor skills in normal individuals and for rehabilitating patients with motor disorders. In this paper, the influence relationship between the brain network of the brain motor system and the relevant motor intervals was investigated by collecting EEG signals during finger motor execution and motor imagery from 11 subjects. To address the problem that Granger causality can only reflect the interaction between two temporal variables, a conditional Granger causality analysis was introduced to analysis the brain network relationships between multiple motor compartments. The results showed that the brain network map of finger motor execution had more effective connections than that of finger motor imagination, and it was found that there were effective connection loops between left PMA and left MA, left MA and left SA, and left SA and right SA for both finger motor execution and motor imagination, and the most important connection in motor function was from premotor area to primary motor area.
