Using the system to evaluate wheel rotation fluidity. a As noted previously in video recordings [10], during the beginning of the running-wheel training (i.e. when naive rats are first exposed to the running wheel), rats are unable to run with an appropriate speed to remain at the bottom of the wheel. As a result, the rat often moves too fast or too slow relative to the speed of the wheel, thus resulting in poor wheel rotation fluidity (i.e. “step-like deflections” indicated by arrows in the trace). However, rats rapidly learn to remain in the bottom while running. b Summarized step-like deflection data for 5 initial rotations (purple) and 5 subsequent rotations (white) illustrating that despite the same number of rotations, there is clear quantitative differences of how these 5 revolutions are performed. Asterisk denotes p < 0.05
