Repetitive discharges from human motor nerves after ischaernia and their absence after cooling

The phenomena which occur in nerves in the post-ischaemic state may be those observed sub-jectively as paraesthesiae, or those of which objective evidence is provided by the electromyogram as repetitive muscle action-potentials. Both are believed to be due to iterative discharges occurring in the nerve, either spontaneously or in response to action currents evoked by normal or electrical stimuli. In both groups, however, despite many ingenious experiments, authors have disagreed on the site of origin of the repetitive discharges. The purpose of the present study was to seek further evidence on this point, and to investigate the possibility that similar discharges occur during cooling and the subsequent return of the nerve t
