A recent study suggests that recalling learned movements like tying shoelaces or playing musical instruments activates rapid brain activity.

The study, published in the Journal of Neuroscience on Feb. 1, utilized functional magnetic resonance imaging (fMRI) to observe brain activity as participants played simple melodies on a keyboard.

fMRI monitors brain activity by tracking oxygenated blood flow, providing insights into brain function.

Brain Activity Patterns during Movement Recall

Participants learned one-handed keyboard melodies over several days and then performed them from memory in the fMRI scanner. Brain scans during the planning phase showed heightened activity in movement-related regions of the cerebral cortex's outer surface. Specific brain activity patterns corresponded to note sequences and durations, indicating a unique pattern for each movement.

Integration of Movement Patterns

The process of planning and executing movements involves separate patterns that integrate during execution, forming a distinct brain activity pattern.

This integration creates a unique representation for each movement sequence, with the brain transitioning from handling individual elements to considering them as a single unit during execution.

Challenging Established Theories

Contrary to established theories suggesting a hierarchy in movement control regions of the cortex, the study found that areas previously considered 'low-level' in movement control constantly update based on movement challenges.

Regions like the premotor and parietal areas store high-level movement information, while the primary motor cortex dynamically adjusts based on movement order and timing challenges.

Applications in Motor Disorders and Skill Acquisition

The research on muscle memory extends to studying disorders like dyspraxia and aiding motor skill recovery post-stroke. Further research on motor learning involves exploring how trained musicians' brains differ in movement recall compared to novices.

Highly trained individuals may have motor sequences 'hardwired' in the cortex, leading to differing rapid adjustments in movement features.
