From: M-Current Expands the Range of Gamma Frequency Inputs to Which a Neuronal Target Entrains

Simulations of (1) with h-current instead of M-current. The expression of the h-current used here is the same as the one used in [37]. A: The cell with h-current (\(g_{h}=2\), \(I_{\mathit {ton}}=-6\), \(b=0\)) can \(1:1\) phase-lock to 32 Hz input while the cell’s natural frequency is 34.5 Hz. But the spikes (blue) precede the input (red). B: Same as A, but add the theta input and reduce the tonic current so the natural frequency is the same at 34.5 Hz (\(g_{h}=2\), \(I_{\mathit {ton}}=-10\), \(b=4\)) at the peak of theta input. The cell with h-current (blue) has the same firing frequency as the input (red). Unlike the cell with M-current, where the spikes always occur after the input (Fig. 1A), some spikes of the cell with h-current occur before the input
