Objectives:The aim of this study was to examine the relation between the P300 event-related potential and the fi nger tapping test (FTT) scores in healthy male volunteers. Methods:The electroencephalograms (EEG) of 30 male subjects were obtained while they performed the oddball paradigm and the FTT. Results: The P300 latencies were correlated negatively with the FTT scores. Conclusion: The signifi cant correlation between the FTT scores and the P300 latencies lends support to the theory that dopaminergic activity may be mediated in P300 generation.
