Table 1Intrinsic and sAHP properties

	Granule cells n = 9	Pyramidal cells n = 10
Resting potential (mV)	−75 ± 3	−57 ± 2
Input resistance (MΩ) RN	190 ± 36	132 ± 44
Time constant (ms) τm	21 ± 7	42 ± 7
Threshold (mV)	−46 ± 1	−44 ± 2
Number of action potentials	27 ± 5	17 ± 6
SAHP amplitude (mV)	2.0 ± 0.5	8.2 ± 0.9
Latency to peak (ms)	580 ± 190	340 ± 130
Half amplitude decay time (s)	1.4 ± 0.4	2.0 ± 0.5
Charge transfer (pAs)	33 ± 11	232 ± 59

All intrinsic properties were characterized by injection of a series of 1000 ms de- and hyperpolarizing current pulses from a holding potential of −70 mV and −60 mV in GCs and PCs, respectively. For sAHP properties, all neurons were manually clamped at −60 mV. All parameters, except threshold, reach the level of statistical significance.
