Hypothesized brain activations during Naive, Practiced, and Novel maze tracing as well as during Fast Square tracing and hypothesized increased (+) and decreased (−) activations when Square Fast is subtracted from maze tracing

Practice state	Maze activation	Square Fast activation	Maze–Square Fast activation
Naive, no prior practice	R premotor R par. (7 + 40) L cerebellum	SMA	(−) SMA (+) R premotor (+) R par. (7 + 40) (+) L cerebellum
Practiced, after 10 min on same maze	SMA	SMA	No activation
Novel, after practice but with new maze	R premotor R par. (7 + 40) L cerebellum	SMA	(−) SMA (+) R premotor (+) R par. (7 + 40) (+) L cerebellum
