A–D: Effects of weak Ih channel modulation on apical dendritic excitability in Almog and Hay model when a faster Ih inactivation was assumed. The experiments of Fig 4.6 were repeated using 4 times smaller time constants of Ih inactivation (τ∞) than in the original Hay and Almog models. See Fig 4.6 for details. E: Threshold current amplitudes for 2-ms square-pulse inputs at the apical dendrite at different distances from the soma using 4 times smaller time constants of Ih inactivation. Black: Hay-model control neuron, blue: Hay-model neuron with Ih blockage. The amplitudes are very similar to those with the original time constants (Fig 2G). (PDF)
