Prosencephalic projections from the cerebellar and vestibular nuclear complexes in the turtle Pseudemys scripta elegans were investigated with anterograde tracing. Following injections of 35S-methionine at various locations within the cerebellar and vestibular nuclear complexes, labeled ascending fibers were found to arise from the lateral cerebellar and the rostral (superior and/or dorsolateral) vestibular nuclei. The great majority of these fibers coursed within the ipsilateral ascending periventricular tract. There were possible terminations in the hypothalamosuprapeduncular region, the ovalis-complex, and the nucleus commissuralis anterior, but scarcely any indication of terminal labeling within the dorsal thalamus. The labeled fibers, however, continued rostralward, entered the lateral forebrain bundle, and terminated in the anterior dorsal ventricular ridge--in all but one case, exclusively ipsilaterally. The terminal area within the lateral division (referred to as area L) of the anterior dorsal ventricular ridge was sharply delimited, being situated ventrolateral to the visually oriented area D of the anterior dorsal ventricular ridge (Balaban and Ulinski, '81), medial to the lateral cortex, and ventral to the pallial thickening (motor pallium of Johnston, '16). The findings are compared with related ones in mammals, particularly those pertaining to telencephalic somatosensorimotor regions and their interactions with the vestibular nuclear complex and the cerebellum.
利用顺行示踪技术研究了秀丽锦龟小脑和前庭核复合体向端脑的投射。在小脑和前庭核复合体内的不同位置注射³⁵S-甲硫氨酸后，发现标记的上行纤维起源于外侧小脑和吻侧（上侧和/或背外侧）前庭核。这些纤维绝大多数在同侧的上行脑室周束内走行。在下丘脑上脚区、卵圆复合体和前连合核可能有终末，但在背侧丘脑内几乎没有终末标记的迹象。然而，标记纤维继续向吻侧延伸，进入外侧前脑束，并终止于前背侧室嵴——除一例以外，均仅终止于同侧。前背侧室嵴外侧部（称为L区）内的终末区域界限清晰，位于前背侧室嵴视觉导向区D的腹外侧（巴拉班和乌林斯基，1981年），外侧皮质的内侧，以及皮质增厚（约翰斯顿1916年的运动皮质）的腹侧。将这些发现与哺乳动物中的相关发现进行了比较，特别是那些与端脑躯体感觉运动区及其与前庭核复合体和小脑相互作用有关的发现。
