The research shows that the primary motor area (M1) has overlapping neural representations for motor execution and motor imagery.
Using functional magnetic resonance imaging, accuracy of classifying finger movement in M1 was higher than chance for both execution and imagery.
A replication study confirmed the neural representation similarities in hand M1 between the two tasks.
This finding enhances our understanding of how motor execution and imagery are connected in brain function.
