Development of theta rhythmicity in entorhinal stellate cells of the juvenile rat.

abstract：:1. Current- and voltage-clamp studies were conducted on isolated rat adrenal chromaffin cells to identify the voltage-dependent ion channels mediating inward currents. 2. Mean resting membrane potential of the isolated cells was -62 +/- 3 (SE) mV. Evoked action potentials were both Na+ and Ca2+ based, and whole cell v...
