Electrophysiological properties of CA1 hippocampal neurons (pre-LTP recordings)

	Low LG (n = 10)	High LG (n = 11)
Vehicle treatment
Max fEPSP amplitude (mV)	−2.16 ± 0.19	−2.98 ± 0.17**
Max stimulus intensity	211 ± 7.36	216 ± 4.82
100 nm Corticosterone treatment
Max fEPSP amplitude (mV)	−2.56 ± 0.33	−2.64 ± 0.09
Max stimulus intensity	203 ± 8.47	216 ± 4.64

Pre-LTP recording measurements. Maximal fEPSP amplitude evoked by low-frequency stimulation was significantly lower in offspring of low LG versus high LG mothers, whereas half-maximum stimulus intensity values were comparable between both groups in response to vehicle treatment. Conversely, maximal fEPSP amplitude evoked by low-frequency stimulation and half-maximum stimulus intensity values did not differ between low and high LG phenotypes after high corticosterone (100 nm) treatment.
