|Basic membrane responses at −60 to −50 mV (n = 13) a|
|Input resistance||602 ± 183 MΩ|
|Time constant||2.3 ± 0.36 ms|
|Properties of unitary EPSPs at −70 to −60 mV (n = 11) b|
|Amplitude of maximal EPSPs||8.7 ± 2.1 mV|
|Time-to-peak||0.95 ± 0.17 ms|
|Half decay time||5.5 ± 1.7 ms|
|Coefficient of variation for unitary EPSPs, evoked and spontaneous (n = 8) c||10.7 ± 2.9%|
↵ aInput resistances and time constants calculated from the membrane responses to hyperpolarizing current steps with a duration of 300–1000 ms.
↵ bEPSP properties were calculated on 30–200 spontaneous EPSPs from 11 different cells.
↵ cThe coefficient of variation (CV = SD/mean of the EPSP amplitude) was calculated from EPSPs in the largest, distinct EPSP amplitude group in four cells (at least 30 EPSPs) and from the EPSPs evoked from just suprathreshold mossy fiber stimulation in four cells (at least 16 evoked EPSPs, failures excluded). The CV values were similar and therefore pooled.
