| Outline of Final Research Achievements |
The cerebellum is interconnected with the association areas in the frontal and parietal cortices, and therefore is thought to play roles in non-motor cognitive functions such as time perception and prediction. We devised a variety of psychophysical tests to evaluate cerebellar cognitive functions and examined the performance of patients with spinocerebellar degeneration (type 6). We found that some behavioral parameters differed significantly between patents and matched controls, and correlated with the volume of lateral cerebellum (Crus I and II). Furthermore, we trained monkeys in similar behavioral paradigms for future physiological studies.
