Dendritic Ih loss begins within 1 hour after SE, and persists for at least 1 month. A, Ih amplitudes at maximal activation obtained from 1 hr and 1 d post-SE animals were significantly reduced compared to control. Representative current traces are shown at voltage commands of ∼150 mV. Summary data at 1 wk are from (Jung et al., 2007), and at 1 mo from (Jung et al., 2010). B, Voltage-dependent activation of Ih at 1 hr and 1 d post-SE was similar to control. Diagram shows approximate location of dendritic recordings.
