HC-030031 has no effect on mechanical thresholds, conduction velocity, or electrical thresholds in C fibers. A) Median von Frey thresholds in C fibers before and after 10 min treatment of the receptive field with vehicle or HC-030031 (100 μM). Y-axis bars represent the median and 25^th and 75^th percentiles for each group. B) Average conduction velocity of C fibers before and after 10 min treatment of the receptive field with vehicle or HC-030031. Y-axis bars represent the mean and SEM for each group. C) Average electrical threshold of C fibers before and after 10 min treatment of the receptive field with vehicle or HC-030031. Y-axis bars represent the mean and SEM for each group. The "after" measures were made in the presence of either vehicle or HC-030031.
