Fig. 4.

(A) Firing efficiency (FE) versus sweep number for four fibers and three stimulus levels per fiber. For each sweep, FEs were computed by collapsing fiber activity across the entire epoch of each 300-ms pulse train. The number in the top right corner of each graph indicates stimulus level in mA. (B) Response probabilities for two fibers over the entire time of data collection. Vertical lines separate data for each file (i.e., set of repeated pulse trains) and the numbers at the top of each graph indicate stimulus level in mA.
