From: M-Current Expands the Range of Gamma Frequency Inputs to Which a Neuronal Target Entrains
The I-cell with M-current has a larger \(1:1\) phase-locking region (A, 29 Hz to 49 Hz) than the I-cell without M-current (B, 34 Hz to 49 Hz). The I-cell with M-current can phase-lock to pulses slower than its natural frequency (34 Hz). With pulses faster than the \(1:1\) phase-locking band, the spikes of the I-cell with M-current always align with incoming pulses (sparse entrainment). Without the M-current, the I-cell has phase lag when being forced by faster pulses. Voltage traces of the I-cell are in blue. External pulses are in red. External pulse frequencies are labeled on the left
