Amplitude of Ih is not related to rhythmicity but to firing frequency. Ai, Plot of the average Ih-induced sag amplitude for the three different classes of dCIN as measured under current-clamp conditions (hyperpolarizing step to −110 mV). Aii, Scatterplot showing the insignificant relationship between Gmax and rhythmicity (r) in seven neurons recorded under voltage-clamp conditions. B, Distribution of the Ih-induced sag amplitude measured under current-clamp conditions for different ranges of firing frequencies in rhythmic dCINs.
