Comparison of characteristic of smooth pursuit in left-handed and right-handed subjects

In a study on healthy young adults with the use of a stroboscopic stimulation, estimation of the efficiency of smooth pursuit has been performed. The influence of manual function asymmetry on smooth pursuit has been studied. It has been shown that markedly right-handed (“strong right-handed”) persons display a high efficiency of smooth pursuit of stimuli moving horizontally in the rightward and leftward directions with velocities of 20°/s and 25°/s. Left-handed persons track similar stimuli, on average, worse than the “strong right-handed” ones. The influence of manual function asymmetry on the dependence of the smooth pursuit efficiency on the moving stimuli direction (left to right or right to left) has not been observed.
