我们描述了猴子上丘中与视觉刺激和眼球运动有关的一系列细胞(4，5，17)。通过上丘和视觉感受野的垂直穿透，这些细胞的运动场都是地形图组织的，都位于对侧视野的同一区域。在本实验中，我们破坏了与视野某一区域相关的一小部分上丘，以了解它是否参与了视觉信息向眼动系统的传递。我们用微电极记录了小脑丘中的细胞，定位了这些细胞在视野中的感受野，并让猴子扫视到视野中这个区域内的光点。然后，我们用相同的微电极消融通过丘脑的这一电流部分，并测定猴子对视野中不再是苔藓的部分进行扫视的能力。代表
WE HAVE DICSCRIBED a series of cells in the monkey superior colliculus related to visual stimulation and eye movement (4, 5, 17). III a vertical pene tration through the superior colliculus &e visual receptive fields and the movement fields of these cells are all topo-graphically organized and all lie in the same area of the contralateral visual field. In the present experimen ts we destroyed a small volume of superior colliculus related to one area of the visual field in order to see if it was involved in the transfer of visual information to the eye-movement system. We recorded from cells in the colliculus with a microelectrode, located the receptive fields of these cells in the visual field, and had the monkey make saccades to spots of light within this area of the visual field. Then we ablated this passing current part of through the the colliculus by same microelectrode and determinecl how well the monkey could make saccades to points in the part of the visual field which was no longer liculus. represented
