Using the method of intra-axonal injection of horseradish peroxidase, functionally identified afferent fibers from three slowly adapting (Type I) receptors and one Pacinian corpuscle in the glabrous skin of the hind paw of the cat were stained. Electron microscopic observation of the terminals of these fibers revealed predominantly axodendritic asymmetric synapses containing round, clear vesicles. Multiple synapses on a single dendrite were observed, separated by as little as 900 mm from one another.
运用辣根过氧化物酶轴突内注射法，对猫后爪无毛皮肤中来自三种慢适应（I型）感受器和一个环层小体的功能已明确的传入纤维进行了染色。对这些纤维终末的电子显微镜观察显示，主要是含圆形清亮小泡的轴-树突不对称性突触。在单个树突上观察到多个突触，彼此间的间距小至900微米。
