一种新的技术，开发了稳定的，长期的记录，从组的个人初级传入神经元在自由行走的猫。一些罚款，灵活的电线插入背根神经节通过一个小椎板切开术在腰椎。每根导线的切割端可以记录1-3个背根神经节神经元的稳定和可分离的动作电位;每个单元通常保持1-4天。广泛的有髓鞘的体感传入（传导速度为30-120米/秒）进行了研究，在运动。大多数皮肤和本体感觉传入研究的步骤周期组件的复杂组合的敏感的监视器，其放电模式往往是难以预测的现有信息。
A new technique was developed for stable, long-term recording from groups of individual primary afferent neurons in the freely walking cat. A number of fine, flexible wires were inserted into dorsal root ganglia via a small laminotomy in the lumbar spine. The cut end of each wire can record stable and separable action potentials from 1-3 dorsal root ganglion neurons; each unit typically held for 1-4 days. A broad range of myelinated somatosensory afferents (conduction velocities of 30-120 m/s) were studied during locomotion. Most cutaneous and proprioceptive afferents studied were sensitive monitors of complex combinations of step-cycle components, and their firing patterns would often be difficult to predict from existing information.
