The PC response was different depending on the stimulated sector (Figure 6A). When excitatory pf and inhibitory stimulations were delivered to dendritic sector I or IV, the PC BPRs were similar to those obtained using a random distribution of synapses. However, when excitatory stimulation was delivered to sector II or III, the pause was much longer than usual (over 250 ms in the Z+ model). When aa was substituted to pf stimulation, the responses were similar except for sector I, which showed a longer pause with aa then pf stimulation (the reason of this will be explained below). The difference between sectors was poorly sensitive to the location of inhibition, and BPRs did not change remarkably when inhibition was moved to sectors different from the one that was excited by pf synapses (Figure 6B). Similar response properties were observed in the Z− model, although pauses were shorter (data not shown).
