| Outline of Final Research Achievements |
The gray matter volume in the visual cortex areas associated with peripheral vision showed a positive correlation with performance on the 3D multiple object tracking task. Additionally, non-invasive cathodal stimulation to the visual areas in the occipital lobe by transcranial direct current stimulation demonstrated the potential to further enhance task performance. Furthermore, the results from observing basketball free-throw actions revealed that, regardless of basketball experience, the excitability of the corticospinal pathway, which connect primary motor cortex to spinal motor neurons, was not facilitated during video observation at a slower playback speed compared to normal playback speed.
