Effect of BIBN4096BS microiontophoresis on SSS-evoked firing: Post-stimulus histograms showing that supramaximal electrical stimulation (50 × 250 μs) of the SSS via bipolar platinum hook electrodes recruits units in the trigeminocervical complex responding to the stimulus with a latency peak of 12 ms (panel a) that is inhibited immediately after microiontophoresis of BIBN4096BS (20 mM, pH 5.8; +60 nA for 300 s) (panel b). The apparent response within the first 0.2 ms is part of the stimulus artefact.
