Dynamics of the Cortical Motor Representation of the Extensor Digitorum Communis Muscle after Motor Imagery Training Using a Brain–Computer Interface: a Controlled Study

The mechanisms of the organization of goal-directed movements in the human arm have received insufficient study. The processes of cortical reorganization on the background of learning new skills and rehabilitation after central nervous system disease are of particular interest. Studies of the motor...

Summary:The mechanisms of the organization of goal-directed movements in the human arm have received insufficient study. The processes of cortical reorganization on the background of learning new skills and rehabilitation after central nervous system disease are of particular interest. Studies of the motor system and recording of neurophysiological parameters determining the kinematic characteristics of movements at the cortical level use navigated transcranial magnetic stimulation. The present study of 20 healthy volunteers randomized to study and control groups assessed resting motor thresholds, cortical motor representation zones of the extensor digitorum communis muscle in terms of areas and weighted areas, and the displacement of the centers of gravity on the background of training to motor imagery using a brain–computer interface. No significant differences were found between these parameters in the study group and the control group.
