Abstract: Nine kittens after a cordotomy on one side were lesioned respectivelyon the controlateral side to either the restiform body or the brachiumconjunctivum.Afterwards,the HRP was injected into the anterior orposterior lobe of the cerebellum respectively.After 3-4 days' survivaltime the animals were perfused and the retrogradely labeled neuronscaudal to L_{2/sub> were observed.The results were as follows:The columnof Clarke (CC,L3-L4)and the neurons in laminae Ⅳ-Ⅵ (L3-L5)sentuncrossed fibers passing through the restiform body.The dorsolateralnucleus (DL,L3-L5)sent crossed fibers projecting to the cerebellum bypassing through the brachium conjunctivum.The axons of theventrolateral nucleus (VL,L4-L5)and the spinocerebellar neurons inlateral part of lamina Ⅶ (L3-L4)had the same fiber courses as DL,but VL neurons only terminated in the anterior lobe.The fibersprojected by neurons in medial part of lamina Ⅶ (L6-Cal)were crossedand passed through the restiform body.The neurons in medial part oflamina Ⅷ (L3-L6)sent uncrossed fibers passing through the brachiumconjunctivum and projected to the anterior lobe.The ventromedialnucleus (VM,S1-Cal)sent crossed fibers by passing through therestiform body.The results in present study indicate that there existsome groups of neurons belonging to those of the dorsal spinocerebellartract (DSCT)in addition to neurons of the ventral spinocerebellartract (VSCT).}
