Abstract
Publisher Summary This chapter discusses lens accommodation-related and pupil-related unit activities in anesthetized cats. Nineteen of 146 units in posteromedial lateral suprasylvian (PMLS) discharged in synchrony with lens accommodation, papillary constriction or pupillary dilation. Lens accommodation, pupillary constriction or pupillary dilation were synchronized only occasionally with each other in this chapter, which was conducted under anesthesia and without any visual stimulation. The good correlation between these variables supports the notion that lateral suprasylvian area (LSA) contributes to the central nervous control of these intraocular muscular movements. The activities of most of these units also discharged in prominent synchrony with only one of these three intraocular muscular movements. The close parallelism of unit activities and effects of microstimulation favors the notion that LSA plays an important role in controlling intraocular muscular movements such as accompany lens accommodation and papillary constriction.
