Multiple connections between CA3 and CA1 pyramidal cells and GABAergic cells and CA1 pyramidal cells in young adult rats. (A1) A typical recording at -80 mV from a pyramidal cell, upper trace shows AMPA sEPSCs under control conditions and lower trace shows mEPSCs after wash-in of TTX. (A2) TTX reduces the AMPA EPSC amplitude by 5.9 ± 0.8 pA (P = 0.004, n = 8, two-tailed paired t-test). (A3) TTX reduces AMPA EPSC frequency by 1.5 ± 0.4 Hz (P
