Publication facts (s) having Smotherman MS, Narins PM (1999) as Paper having this fact

1 Whole-cell patch-clamp recordings showed that variations in the kinetics of the outward current contribute substantially to the determination of resonant frequency
2 Whole-cell patch-clamp recordings were used to identify and characterize ionic currents in isolated cells. Most cells possessed a slowly activating IK, which is approximately 80% inactive at rest. In a small subset of cells, IK was replaced by an IA. It is suggested that the kinetic properties of the ionic currents argue against electrical tuning
