The Promise of Discovery Season 5, Episode 4

This research explored how combining visual perception with motor practice—specifically drawing unfamiliar symbols—leads to lasting brain changes that support learning. Participants trained by drawing new letter-like symbols over four days while researchers tracked their brain activity using fMRI scans before, immediately after, and one-week post-training. The after-training scans revealed significant differences in activity within several brain regions—including the motor cortex—during the perception of trained compared to untrained symbols that were greater one-week post-training. This suggests that hands-on, visual-motor learning builds long-term changes in how the brain processes visual information, with potential implications for educational strategies and interventions.
