The IB cell may mode-lock without phase-locking to the input. (a) Membrane potential of the various cells, as a function of time modulo seven input periods (see also Fig. 15(b)). Here input frequency is 62.1 Hz. The SI cell fires periodically, twice in every seven input periods. The FS and IB cells fire only approximately periodically. There is always a single IB burst per SI interspike interval. In particular, the IB cell always bursts twice in every seven input cycles. (b) Histogram of IB interburst interval length. (c) Input phase (time from last input pulse) when the IB cell fires
