A transient voltage-dependent outward current in cultured cerebellar granules.
Granule cells were dissociated from rat cerebella with a procedure that yields a 98% pure cell population. Potassium currents in these cells were studied using the patch-clamp technique. Depolarizing pulses of 10 mV step and 100 ms duration from a holding potential of -80 mV elicited two different potassium outward currents: a transient, low-voltage activated component and a long lasting, high-...
متن کاملVoltage-dependent outward K+current in intermediate cell of stria vascularis of gerbil cochlea.
A voltage-dependent outward K+(KV) current in the intermediate cell (melanocyte) of the cochlear stria vascularis was studied using the whole cell patch-clamp technique. The KV current had an activation threshold voltage of approximately -80 mV, and 50% activation was observed at -42.6 mV. The time courses of activation and inactivation were well fitted by two exponential functions: the time co...

متن کاملUse-dependent features of 4-aminopyridine block of transient outward current in rat ventricular myocytes.
The inhibition of the calcium-independent transient outward current (Ito) by the widely used blocker 4-aminopyridine (4-AP) was studied in adult Wistar rat ventricular myocytes, enzymatically isolated and voltage-clamped in the whole cell configuration using patch-clamp pipettes. 4-AP at 1 mmol/l concentration caused complete steady-state block of Ito at resting or hyperpolarized voltages. The ...
متن کاملEarly outward current in rat single ventricular cells.
Voltage clamp experiments were conducted using single ventricular myocytes which had been dissociated enzymatically from adult rat hearts in order to examine further the membrane currents which contribute to the unusual plateau of the rat action potential. Membrane currents were recorded, using a single microelectrode (switching) voltage clamp circuit. From holding potentials near the resting p...
