1. Extracellular application of ATP generates two whole-cell currents in toad gastric smooth muscle cells: an immediate inward non-selective cation current (due to the activation of a P2X or P2Z-like receptor) and a slowly developing outward K+ current. The inward non-selective cation current depends on the continuous presence of ATP while the outward K+ current can last for minutes after ATP application ceases.
