A. Representative traces for B and C, showing evoked AMPAR- and NMDAR-mediated EPSCs (collected at −60 mV and +40 mV, respectively) in neurons from inactive control-, GSK3α or GSK3β inhibitor-treated slices (all at 10 µM). Slices were incubated with each compound for 1 hour before recording, and during whole-cell recording itself. Compounds were also included in the internal solution of the recording pipette (all at 10 µM).
