Right hemispheric contribution to motor programming of simultaneous bilateral response.
The purpose of this study was to verify the hypothesis that the motor program which integrates the left- and right-hand responses in the bilateral reaction time (RT) task is located in the right hemisphere. 8 female and 50 male students performed bilateral simultaneous RT tasks to lateralized light stimuli. Uncrossed RT based on the relationship between the unifying center in the right hemisphere and hemifield stimulus was shorter than crossed RT for the bilateral response. Therefore, the hypothesis was supported. Some areas of the right hemisphere contributed to unification of the movements of the right and left hands for bilateral movements in reaction time.
