Figure 7.

A, B, Response of the same PY neuron as in Figure 6, and of a pyloric neuron model with a slowly activating and deactivating potassium current, to the same series of stimulation patterns as in Figure 6. All figure labeling conventions are the same as in Figure 6. The slow potassium model much better reproduced neuron activity. C, Summary of model and neuron steady-state rebound delays for stimulation patterns in A and B with a 50:50 duty cycle. The original model (black) showed no change in rebound delay, but in both the real neuron (red) and the slow potassium model (green), steady-state rebound delay increased with cycle period.
