Table 1. Effect of corticosterone on frequency, amplitude, and decay time of mEPSCs in CA1 hippocampal neurons.

Condition	mEPSC frequency, Hz	mEPSC amplitude, pA	τ of decay, s
Before corticosterone	0.85 ± 0.14	22.8 ± 2.3	17.5 ± 1.6
During corticosterone	1.33 ± 0.25*	24.5 ± 1.9	15.8 ± 0.4

All values represent the mean ± SEM, based on a total of 3,242 events from five cells. Corticosterone significantly (*, P < 0.05) enhanced the mEPSC frequency (determined between 5 and 10 min after application was started), whereas the amplitude and time constant of the decay (based on a monoexponential fit) remained unaffected. Control data were collected between 5 and 0 min before corticosterone application was started.
