Fig. 4. Examples of the effect of lateral PB block on mechanically evoked, reflex-related activity of ON- and OFF-cells.

Fig. 4

Representative examples show ON- and OFF-cell activity and associated EMG during trials using 26, 60, and 100 g von Frey probes both in baseline and during PB block. A baseline (top-trace) and block trial (lower trace) are shown for each force. Reflex-related changes in firing were substantially reduced in both cases, and even eliminated for the ON-cell. Period of von Frey fiber application (8 s) is shown below each trace, with arrowhead indicating behavioral responses, which occurred in response to 60 and 100 g stimuli in baseline.
