Activity alters the intrinsic properties of cultured stomatogastric ganglion neurons. (Inset) Hyperpolarizing current pulses trigger a depolarizing sag and a postinhibitory rebound burst. V, membrane potential; and I, current pulse. (Right) The top trace shows neuronal activity before stimulation; the middle trace shows neuronal activity after 1 hr of stimulation using the protocol in the Inset; and the bottom trace shows neuronal activity 1 hr after the stimulation was stopped.
