Objective: Basal ganglia are important structures at motor motional control. In this study we aimed to reveal possible auido and visual reaction times relation with basal ganglia by using vol- umetric stereological analysis related with basal ganglia, which designed for pathological situation that the main motor motion- al cyclus disorders, at a speedy reaction time group of elite sports- man comparing with sedanters.

Methods: Right handed elite 19 sportsman whom 19–25 years old and right handed sedate 20 person whom 18–28 years old two groups partake to our study. Visual and auditory reaction times, stereological basal ganglia volumetry were evaluated for both groups.

Results: The mean of the visual reaction time found higher then auditory reaction time in sportive group. The left basal ganglia volumetry found higher then the right side in both of the study and control group. Auditory reaction time was signif- icantly decreased in elite sportsman compared to sedate cases.

Conclusion: We decide our study satisfy morphometric clinical data to literature.
