A tilted rotational stimulation improves the gait of a cerebellar mutant mouse : The staggerer.

A titled rotational stimulation was given daily from birth to normal and cerebellar staggerer mutant mice. At weaning time the ability to ambulate on a holed floor was measured. An increase in neither the speed nor the total exploration was demonstrated but the ability to avoid holes was significantly improved for both groups. In this experiment, the mutant appeared to be more sensitive to the enrichment factor than the normal.
