本文报道了供应猴（M. nemestrina）食指进行了评估，使用组织学和神经生理学程序的组合。该估计是基于A β的总数计数。在近节指骨水平的指掌侧神经中的有髓纤维，证实了大多数A β。猴指掌侧神经中的纤维是机械感受性传入纤维，基于398根纤维的样本，估算了指掌侧神经中快适应纤维、慢适应纤维和环层机械感受性纤维的比例，并估算了由指掌侧神经支配的无毛皮肤的面积。中节指骨指腹和皮肤的神经支配密度，快适应纤维为178和80/cm ~ 2，慢适应纤维为134和46/cm ~ 2，Pacinian纤维为13/cm ~ 2。
The innervation densities of mechanoreceptive fibers supplying the ridged glabrous skin of the middle and terminal phalanges of the monkey''s (M. nemestrina) index finger were estimated using a combination of histological and neurophysiological procedures. This estimate was based on a count of the total number of A.beta. myelinated fibers in the palmar digital nerve at the level of the proximal phalanx, on demonstrating that the majority of A.beta. fibers in the monkey''s palmar digital nerve are mechanoreceptive afferents, the estimation, based on a sample of 398 fibers, of the fraction of rapidly adapting, slowly adapting and Pacinian mechanoreceptive fibers in the palmar digital nerve and the estimation of the area of glabrous skin innervated by the palmar digital nerve. The estimated innervation density of the finger pad and the skin of the middle phalanx was 178 and 80/cm2 for rapidly adapting fibers, 134 and 46/cm2 for slowly adapting fibers and 13/cm2 Pacinian fibers of both phalanges, respectively.
