Abstract
Recent studies of the anatomy (McMasters et al., 1966), the electrophysiology (Highstein and Ito, 1972), and the behavioral effects of electric stimulation and selective destruction (Tokumasu et al., 1969; Uemura and Cohen, 1972) demonstrated that the superior vestibular nucleus has an essential role for mediating the eye movement of anterior semicircular canal type, i. e. upward movement in the ipsilateral eye and rotatory movement in the contralateral eye. This suggests that an understanding of function of the nervous system should be made by the results which were obtained from various lines of experiment and were able to reach the ultimate verification. The importance of behavioral study using newly developed techniques was also stressed to utilize present and future accumulation of the basic knowledge for the diagnosis and treatment of disorders of the nervous system.
