Article Title: Action potential conduction in the terminal arborisation of nociceptive C-fibre afferents
doi: 10.1113/jphysiol.2002.028712
Figure Lengend Snippet: Top trace shows an original nerve recording in response to an electrical stimulus in the innervation territory of the impaled fascicle. Upon repetition at 0.125–0.5 Hz only the evoked action potential is depicted for every trace in successive order from top to bottom (‘falling leaf plot’). Increasing stimulus frequency always gives rise to activity-dependent conduction velocity slowing, which is visible as a latency increase (•) and decreasing stimulus frequency gives rise to recovery (^).
Article Snippet: Single electrical stimuli (0.2 ms, 30–50 mA from an isolated constant-current stimulator, Digitimer DS7) were applied from a pointed steel probe with a small contact surface (1 mm diameter) as a cathode, which was moved on the skin until single C-unit responses, characterised by their long latencies, were obtained.
