Fig. 6. Pevkinin-2 increases the pyloric rhythm-timed activity level of the LP neuron. (Left) Scatter plot of the number of LP neuron spikes/burst in PevK-2 (10^-6 mol l^-1; N=40) as a function of LP neuron activity during saline superfusion. Each data point represents the mean (±s.d.) number of LP spikes/burst from a single experiment during PevK-2 superfusion and its pre-application control. The diagonal, unity line indicates the points at which PevK-2 application and saline superfusion resulted in the same level of LP neuron activity. (Right) PevK-2 (N=32) increased the mean number of LP spikes/burst, relative to saline controls, during the ongoing pyloric rhythm (^*P<0.0001).
