Fig. 6. Histogram showing the performance of wild type and astrotactin null mice in a Rota-rod behavioral assay. Note the consistent significantly (P<0.01) lower performances of astrotactin null mice in all exercises, except on the final day of the acceleration test (#) when compared with age- and size-matched wild-type mice. Batch 1 refers to the first set tests for each mouse and Batch 2 refers to the second test for each mouse.
