Influx of Ca(2+) and Na(+) ions during an action potential can strongly affect the repolarization and the fast afterhyperpolarization (fAHP) if a neuron expresses Ca(2+)- and Na(+)-dependent K(+) currents (K(Ca) and K(Na)). This applies to cockroach abdominal dorsal unpaired median neurons (DUMs). Here the rapid activation of K(Ca) depends mainly on the P/Q-type Ca(2+) current. Adipokinetic hor...
