Visual event-related potentials under different interstimulus intervals in Parkinson's disease: Relation to motor disability, WAIS-R, and regional cerebral blood flow
چکیده انگلیسی
We have introduced S1-S2 paradigm (task S) as well as oddball paradigm (task O) visual event-related potentials (ERPs) under different interstimulus intervals (ISIs) in Parkinson's disease (PD). ERP measurements were correlated with motor disability, WAIS-R, and regional cerebral blood flow (rCBF). The 'group' influence was characterized by longer latency for P300, N200, and reaction time and decreased P300 amplitude in PD. Both P300 latency and reaction time during task O showed significantly longer latency in longer ISI condition. Our results revealed 'ISI' influence on ERPs during task S and significant correlation between ERPs and rCBF in task S.
