选择慢性去传入或去传出的猫后肢神经，研究其所有传入纤维和所有传出纤维的超微结构，以确定不同功能群纤维的结构差异。测量每根纤维的以下参数：髓鞘片层数(n)、轴突周长(s)、外纤维周长(s)和轴突横截面积(A)。纤维被分配到传入组I、II、III或传入组。并可以利用。根据髓鞘片的数量。
The ultrastructure of all the afferent fibers, or all the efferent fibers, was studied in selected nerves from chronically de-afferentated or de-efferentated cat hind limbs to determine the structural differences between fibers of different function groups. The following parameters were measured for each fiber: number of lamellae in the myelin sheath (n), axon perimeter (s), external fiber perimeter (S) and axon cross-sectional area (A). Fibers were allocated to afferent groups I, II, III or efferent groups .alpha. and .gamma. according to the number of lamellae in the myelin sheath.
