Abstract

Pupillary constriction was evoked by systematic stimulation using a microelectrode in the upper medial bank of the middle suprasylvian sulcus in the parieto-occipital cortex of the cat. The pupillo-constrictor area corresponded to the rostral and middle parts of the posterior medial lateral suprasylvian (PMLS) area. This pupillo-constrictor area extended by 2-3 mm along the middle suprasylvian sulcus. It is suggested that this pupillo-constrictor area overlaps or lies in close proximity of a part of the region in PMLS area related to lens accommodation, in which unit activity temporally related to lens accommodation was recorded and from which lens accommodation was evoked by electric stimulation.

摘要

在猫的顶枕叶皮质中，通过使用微电极在中薛氏沟上内侧岸进行系统刺激来诱发瞳孔收缩。瞳孔收缩区对应于后内侧外侧薛氏（PMLS）区的吻侧和中部。该瞳孔收缩区沿中薛氏沟延伸2 - 3毫米。有人提出，这个瞳孔收缩区与PMLS区中与晶状体调节相关的部分区域重叠或紧邻，在该区域记录到了与晶状体调节在时间上相关的单位活动，并且通过电刺激可诱发晶状体调节。
