Fig. 5. Pevkinin-2 increases the speed of the pyloric rhythm. (Left) Scatter plot
of the pyloric cycle frequency during superfusion of PevK-2 (10-6
mol l-1) as a function of the pyloric cycle frequency during saline
superfusion. Each data point represents the mean (±s.d.) cycle
frequency from a single experiment during PevK-2 superfusion and its
pre-application control (N=39). Data points located along the
diagonal, unity line indicate experiments in which PevK-2 application did not
change the ongoing cycle frequency. (Right) PevK-2 (10-6 mol
l-1) application increased the mean pyloric cycle frequency across
preparations (N=39; *P<0.0001).
