| Outline of Final Research Achievements |
Previous studies suggest that temporal information processing is abnormal in patients with neurological disorders, including Parkinson’s disease (PD). We used three tasks to elucidate and characterize the abnormal processing. One tasks was to compare the duration of two sounds (S1 and S2) presented in succession. Another was to reproduce the duration of sound just presented by pressing a button for the same duration of time. The third was to tap the keyboard in synchrony with the tones (duration: 50 ms) that were regularly presented with an interval of 200ms to 5000ms. In all three tasks, performance differed between PD patients and age-mathced normal subjects. We suggest that processing of temporal information is different between PD patients and normal subjects, especially when the time to be processed has a duration longer and shorter than several seconds.
