本研究用逆行细胞变性法观察了7头幼龄驴左侧丘脑的三叉神经丘脑纤维联系。使动物存活15-45天，并根据Klüver-Barrera和thietamine方法对脑干的石蜡切片进行染色。结果发现，三叉神经感觉主核的背侧部分，仅在同侧丘脑横断表现出逆行细胞变化和细胞丢失。就脊髓束核而言，仅在其口部亚核中发现了轻微的变化，主要是对侧。这些研究结果表明，在驴的主要trigeminothalamic投影如下同侧课程丘脑。
In this study the left thalamus of seven very young donkeys was transected and the trigeminothalamic fibre connections were investigated by means of the retrograde cell degeneration method. The animals were allowed to survive for a period of 15-45 days and the paraffin sections of the brain stem were stained according to the Klüver-Barrera and the thionine methods. It was found that the principal sensory trigeminal nucleus exhibited retrograde cell changes and cell losses, in its dorsal part, only at the side ipsilateral to the thalamic transection. As far as the nucleus of the spinal tract is concerned, slight changes were found, mainly contralaterally, in its oral subnucleus only. These findings suggest that in the donkey the main trigeminothalamic projection follows an ipsilateral course to the thalamus.
