Neuronal Currents
  • Properties of K+ outward currents were investigated in human DG cells from 11 specimens obtained from patients with temporal lobe epilepsy. An IK was observed in all cells. The average current density, the time-dependent decay, and the resting membrane characteristics were not significantly different between patients with and without Ammon Horn Sclerosis. The V1/2(inact) was shifted in a hyperpolarizing direction in AHS (-67.7mV) compared with that in hippocampi not showing AHS (-47.7mV) Show Other
  • The properties of outward currents were investigated with patch-clamp in acutely isolated rat DGCs at various postnatal ages and at adulthood (2-3 mo). Kinetic analysis and pharmacological properties showed that IK and IA were present in these cells. IA and IK remained stable with respect to kinetic properties during ontogenesis, but the relative contribution and pharmacological properties varied with age. IA dominated in P5-7 cells whereas IK was prominent in most older cells Show Other
