| Pair No.
|| Amplitude [Base to Peak] (mV)

|1 (n = 9)|
|2 (n = 10)|
|3 (n = 10)|
|4 (n = 7)|
|5 (n = 11)|
|6 (n = 8)|
Values are listed as mean ± SE and n = sample size. Characteristics of unitary excitatory postsynaptic potentials (EPSPs) from 6 pairs of monosynaptic connections between granule cells of rats with mossy fiber sprouting. Means are from 7 to 13 consecutive EPSPs that were evoked by presynaptic action potentials triggered at 1 Hz. Presynaptic action potentials were evoked by fixed amplitude current pulses at 1 Hz. Failures are excluded. Time to peak was measured from the end of the capacitative artifact of the presynaptic action potential to the peak of the unitary event (*) or from the peak of the presynaptic action potential to the peak of the unitary EPSP (†). For definitions of amplitude, rise-time and half-duration, see METHODS.
