(A) Representative traces of action potential in CA1 pyramidal neurons upon varying the injected current from AAG-Con and AAG-KO. (B) Summary data of action potential firing. (c,d) Summary data of resting membrane potential (C) and threshold (D). (E,F) Representative traces of spontaneous EPSCs (E) and IPSCs (F) from AAG-Con and AAG-KO. (G–J) Summary data of amplitude and frequency in sEPSC (G,H) and sIPSC (I,J) derived from 3 mice from each genotype, 9–10 cells. (K) Representative traces of input-output curve in evoked EPSC (Left) and IPSC (Right) from AAG-Con and AAG-KO. (L,M) Summary data of evoked EPSC (L) and IPSC (M). (N) Representative traces of paired pulse ratio (PPR) upon varying the inter-spike-interval (ISI) from AAG-Con and AAG-KO. (O) Summary data of PPR. Student’s two-tailed unpaired t-test (C,G–J) and two-way ANOVA with Sidak test (B,L,M,O). AAG-Con denotes: NFIAfl/fl; Aldh1l1-GFP. AAG-KO denotes: NFIAfl/fl; Aldh1l1-CreER; Aldh1l1-GFP.
