Contribution of delayed rectifier potassium currents to the electrical activity of murine colonic smooth muscle [PDF]

open access: yesThe Journal of Physiology, 1999
1. We used intracellular microelectrodes to record the membrane potential (Vm) of intact murine colonic smooth muscle. Electrical activity consisted of spike complexes separated by quiescent periods (Vm approximately -60 mV). The spike complexes consisted of about a dozen action potentials of approximately 30 mV amplitude. Tetraethylammonium (TEA, 1-10
