The localization of the Purkinje cells in the uvula and nodulus projecting to the vestibular nuclei and the prepositus hypoglossal nucleus (PH) was studied by means of retrograde axonal transport of horseradish peroxidase in cats. Findings indicate a zonal organization in the uvula and nodulus projecting to the vestibular nuclei as follows; the Purkinje cells located in the medial half of the uvula except for the area along the posterolateral fissure project to the middle part of the inferior vestibular nucleus (IV) (middle IV zone); those in the lateral half of the uvula other than the laterocaudal part project to the caudal part of the IV (caudal IV zone); those in the mediorostral part of the nodulus and the middle part of the nodulus project to the middle part of the medial vestibular nucleus (MV) (middle MV zone); those in the lateral part of the nodulus project to the caudal part of the MV (caudal MV zone); those in the medial part of the uvula and nodulus along the posterolateral fissure project to the dorsal peripheral part of the superior vestibular nucleus (SV) (SV zone). There is no specific projection zone in the uvula and nodulus projecting to the lateral vestibular nucleus, the ventral peripheral and the central part of the SV, the rostral part of the MV, the rostral part and the caudal pole of the IV, the caudal one-third of the group f, the group x and the PH.
利用辣根过氧化物酶逆行轴突运输法，在猫身上研究了蚓垂和小结中投射至前庭核及舌下前置核（PH）的浦肯野细胞的定位。结果表明，蚓垂和小结中投射至前庭核的区域呈带状分布，具体如下：位于蚓垂内侧半（沿后外侧裂的区域除外）的浦肯野细胞投射至下前庭核（IV）的中部（IV中部区）；蚓垂外侧半（尾外侧部除外）的浦肯野细胞投射至IV的尾部（IV尾部区）；小结嘴内侧部和小结中部的浦肯野细胞投射至内侧前庭核（MV）的中部（MV中部区）；小结外侧部的浦肯野细胞投射至MV的尾部（MV尾部区）；沿后外侧裂的蚓垂和小结内侧部的浦肯野细胞投射至上前庭核（SV）的背侧周边部（SV区）。蚓垂和小结中不存在投射至外侧前庭核、SV的腹侧周边部和中央部、MV的嘴侧部、IV的嘴侧部和尾极、f组尾侧三分之一、x组及PH的特定投射区。
