In this paper, some of these evidence were reviewed, and a hypothesis was proposed that lateral suprasylvian area (LSA), one of the extrastriate visual cortex in cats, played an important role in controlling lens accommodation. The pattern of fiber connections of LSA and the properties of LSA neurons were in good agreement with the hypothesis. Lens-related neurons in LSA were found; they dishcarged preceding spontaneously-occurring lens accommodation, and lens responses were evoked by microstimulation at their recording sites. Lens-related LSA neurons send their axons directly to the brainstem nuclei closely related to lens accommodation. They were driven by the movement of the visual targets approaching to and/or departing from the nose of the animal, and their discharges were followed by increase of the refractive power of the lens with comparable delays to those found during spontaneous activities. It was proposed that LSA plays one of the essential part to the central neuronal control of lens accommodation in cats.}, pages = {307--312}, title = {焦点調節と大脳視覚領}, volume = {102}, year = {1988} }
