    Abstract:
    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.
