title: Potassium current kinetics in Myxicola axons. Effects of conditioning prepulses.
abstract: In Myxicola giant axons the time constants for activation of the potassium conductance (GK) after prepulses less depolarized than a test pulse are comparable to the time constants for turn off of GK after prepulses more depolarized than the same test pulse. The absolute magnitude of the steady-state level of GK is also independent of prepulse amplitude in Myxicola. The results are contrasted with recent observations on voltage-clamped frog nodes.
