The flocculus of the monkey was mapped with microstimulation methods in chronic preparations. Three types of low threshold, disconjugate eye movements were elicited: (1) a lateral deviation of the ipsilateral eye, (2) a downward deviation of the ipsilateral eye and (3) counterclockwise rotation of the ipsilateral eye. Horizontal eye movements were obtained from folia 2, 3, 4 and 6-10 of the flocculus, and the region eliciting horizontal eye movements was traced in the sagittal plane over a distance of 4 mm in one animal. However, sites flanking these horizontal movement sites produced either vertical movements, rotatory movements or failed to produce a movement of either eye. These findings suggest a zonal organization of flocculus functions in monkeys that is consistent with the differential projections of flocculo-vestibular connections revealed by retrograde tracing studies [2].
在慢性制备的猴子中，采用微刺激方法绘制了绒球图谱。引发了三种低阈值、非共轭眼动：（1）同侧眼的外展，（2）同侧眼的下转，以及（3）同侧眼的逆时针旋转。水平眼动来自绒球的第2、3、4叶和第6 - 10叶，在一只动物中，引发水平眼动的区域在矢状面内追踪了4毫米的距离。然而，这些水平运动部位两侧的位点要么产生垂直运动、旋转运动，要么未能引起任何一只眼睛的运动。这些发现表明猴子绒球功能存在分区组织，这与逆行追踪研究[2]揭示的绒球 - 前庭连接的差异投射一致。
