The Changes in the Hemodynamic Activity of the Brain during Motor Imagery Training with the Use of Brain-Computer Interface

Original language description

With the use of functional MRI (fMRI), we studied the changes in brain hemodynamic activity of healthy subjects during motor imagery training with the use brain-computer interface (BCI), which is based on the recognition of EEG patterns of imagined movements. ANOVA dispersion analysis showed there are 14 areas of the brain where statistically significant changes were registered. Detailed analysis of the activity in these areas before and after training (Student’s and Mann-Whitney tests) showed that the real amount of such areas is five; these are Brodmann areas 44 and 45, insula, middle frontal gyrus and anterior cingulate gyrus. We suggest that these changed are caused by the formation of memory traces of those brain activity patterns which are most accurately recognized by BCI classifiers as correspondent with limb movements imagery. We also observed a tendency of increase in the activity of motor imagery after training. The hemodynamic activity in all these 14 areas during real movements was either approximately the same or significantly higher than during motor imagery; activity during imagined leg movements was higher than that during imagines arm movements, except for the areas of representation of arms.
