从形态学1，2，4，5，12和电生理学3，7，10，1~证明了小脑间位核的前部和后部向红核的大细胞部分发送其轴突。然而，尚未用电子显微镜研究interposito-rubral纤维终止的精确模式，尽管已经提出了电生理数据，表明这些纤维的末端具有轴体性质。本研究的目的是确定红核的大细胞部分的神经元的interposito-rubral纤维的终止的网站。鉴于数据显示，没有来自内侧核或外侧核的纤维终止于大细胞红核2，单个损伤针对中间核或上级小脑脚。在5只成年猫和1只兔子中，通过直径为0.5 mm的不锈钢针（除尖端外绝缘），通过2-3 mA的阳极电流15-30秒，立体定位产生电解损伤;舌头连接到阴极。在其他3只兔子中
It has been demonstrated morphologically1, 2, 4, 5, 12 as well as electrophysiologically3, 7, 10, 1~ that the anterior and posterior parts of the nucleus interpositus of the cerebellum send their axons contralaterally to the magnocellular part of the red nucleus. The precise mode of termination of the interposito-rubral fibers, however, has not been studied with the electron microscope, although electrophysiological data have been put forward suggesting an axosomatic nature of the terminals of these fibers 0. The aim of the present study was to determine the sites of termination of the interposito-rubral fibers at the neurons of the magnocellular part of the red nucleus. In view of the data showing that no fibers from either nucleus medialis or nucleus lateralis terminate in the magnocellular red nucleus 2, a single lesion was aimed either at the nucleus interpositus or at the superior cerebellar peduncle. In 5 adult cats and one rabbit electrolytic lesions were produced stereotaxically through a stainless steel needle of 0.5 mm diameter, insulated except for the tip, by passing an anodal current of 2-3 mA for 15-30 sec; the tongue was connected to the cathode. In 3 other rabbits
