Using the system for wheel-skill learning for evaluating procedural motor learning. a Between wheel-skill evaluation (i.e. between the pre-test and post-test), the training period was monitored continuously for the wheel-locked group (upper trace) and for the wheel-running group (lower trace). The running-wheel group had free access to voluntary wheel running, while the wheel was locked in the locked-wheel group (~40 min session). The wheel running group ran an average of 404 ± 40 m over this period. Vertical changes in the trace with time represent rotations of the wheel (i.e. Δposition ≠ 0°) while a horizontal trace represents no rotation (i.e. Δposition = 0°). b Clear examples of a pre (top) and post (bottom) trace from the same wheel-running rat showing the rotation phase (orange) and the release phase (blue) of wheel-skill learning. c Summarized wheel-skill learning data for a single session for the wheel-locked group (black) and the wheel-running group (grey). Asterisk denotes p < 0.05
