The IB firing rate depends on the input frequency. (a) Ratio of input frequency and IB cell firing (bursting) rate, as a function of input frequency. The IB firing rate often locks to a rational multiple of the input frequency (mode-locking). (b) Membrane potential of the various cells as a function of time, but time is taken modulo five input periods (here input frequency is 42.5 Hz). On each line, 34 traces are superimposed, excluding the transients. All traces fall on top of each other, showing that all cells, including the IB cell, fire periodically, with period equal to five times the input period. In both (a) and (b), the input is exactly periodic (no variation in the interpulse interval—see Sect. 2.2)
