Pooled data for responses to delayed-pulse trains in 9 dogs. A: Te is a linear function of the delay; axis label “C” is nonstimulated control. B: latency of evoked PNG as function of delay. C: E phase stimulus effects on the following Ti as a function of delay. At short delays (0–3 s) that induced short Tes there was a significant decrease in the following Tii+1 values, which returned to control values at the longer delays. D: E phase stimulus effects on the following peak PNG (PPAi+1) as a function of delay. There was a tendency for a decrease in PPA values at the shorter delays similar to the effects on Tii+1. The number of points/delay ranged from 5 to 8 for delays from 0 to 5 s, and fewer at the longer delays. *P < 0.05; ***P < 0.001 for differences relative to control “C.”
