Abstract
A depolarization-induced rise in intracellular Ca2+ in cultured bullfrog sympathetic ganglion cells depended non-linearly on Ca2+ influx and membrane depolarization, spread inwardly faster than that without Ca(2+)-induced Ca2+ release (CICR), and was blocked by dantrolene and ryanodine. Ca2+ entry and a graded activation of CICR thus induce the "Ca2+ transient."
