In Type I responses, a brief pf burst elicited a PC burst terminating in close coincidence with the stimuli (average frequency of 260 Hz) followed by a pause, configuring a typical BPR. The pause between the last spike of the burst and the first spikes when SS activity restarted showed an ISI of 50.46 ± 25.6 ms. Type II responses showed a similar BPR as type I, with the pause showing an average ISI of 48.2 ± 20.4 ms (Steuber et al., 2007). Type III responses showed just the pause, with an ISI of 27.4 ± 3.7 ms. Thus, with this stimulation pattern, BPRs were determined by intrinsic properties of Z+ PCs and were accentuated by molecular layer interneurons.
