Onset latency, peak latency, and peak fluorescence amplitude of fluorescent excitatory postsynaptic potentials (fEPSPs) and fluorescent inhibitory postsynaptic potentials (fIPSPs)  in coronal slices. Onset and peak latencies were longer in deep layers than in superficial layers. Note that onset and peak latencies of fIPSPs were relatively longer than those of fEPSPs.

^*SE was much less than the sampling time.
