We investigated the effects of neck flexion on reaction time in memory-guided and visually-guided saccades. Twelve healthy subjects performed reaction time tasks for visually-guided and memory-guided saccades in neck resting and neck flexion conditions. Reaction times for memory-guided and visually-guided saccades were significantly shortened for the neck flexion condition compared with the neck resting condition. The reduction in reaction time during neck flexion was significantly larger for memory-guided saccade than for visually-guided saccade. These results cleared that the effect of neck flexion on reaction time was larger in memory-guided saccade, which involves higher nervous function, than in visually-guided saccade.
