Outline of Final Research Achievements

The neural mechanisms of conjugate (saccade) and disconjugate eye movement (convergence) have long been considered to be quite different, although the latter mechanism largely remains to be elucidated. This study was aimed at analyzing the neural mechanism of vergence eye movement using anatomical and electrophysiological method. The result showed that the rostral part of the superior colliculus known as the center of saccade generation, is also involved in convergent eye movement. It exerted excitatory effects on medial rectus motoneurons probably via the supraoculomotor area dorsal to the oculomotor nucleus.
