A. Experimental scheme for B-E. Whole-cell patch-clamp recordings were made from nearby pairs of uninfected and infected neurons in CA1 of organotypic hippocampal slices infected with lentivirus carrying shRNAs against GSK3α or GSK3β. EPSCs were elicited with CA3 Schaffer collateral stimulation, and low-frequency stimulation (LFS) was used to induce LTD.
