The activity of mechanoreceptors was studied in normal rats' hindfoot and compared with that of rhizotomised animals. Evoked nerve impulses were recorded from afferent fibres of the n.tibialis. A possible autonomous functioning of decentralised mechanoreceptors, even though in an altered fashion, was shown. The registered shifts comprised a decrease in sensitivity to mechanical stimulation and lower adaptive properties. The findings suggest that the underlying mechanism involves a probable lack of trophic interaction leading to interruption of a link between the CNS and the peripheral nervous system.
在正常大鼠的后足研究了机械感受器的活动，并与神经根切断动物的活动进行了比较。从胫神经的传入纤维记录诱发的神经冲动。结果表明，即使方式有所改变，去中枢化的机械感受器仍可能自主发挥功能。记录到的变化包括对机械刺激的敏感性降低和适应性特性减弱。研究结果表明，其潜在机制可能是缺乏营养相互作用，导致中枢神经系统与周围神经系统之间的联系中断。
