Effect of anisomycin on epileptiform activity elicited by 4-AP in acute hippocampal slices of 3-month-old WT and Tg2576 mice. (A) Representative traces of extracellular field recordings in acute hippocampal slices of 3-month-old WT mice before 4-AP addition (top), in the presence of 50 μM 4-AP alone (middle) and in the presence of 100 μM anisomycin (bottom). (B) Representative traces of extracellular field recordings in acute hippocampal slices of 3-month-old Tg2576 mice before 4-AP addition (top), in the presence of 50 μM 4-AP alone (middle) and in the presence of 100 μM anisomycin (bottom). (C) Quantification of frequency (Hz), interval (sec), and amplitude (mV) of extracellular field recordings in acute hippocampal slices of 3-month-old WT and Tg2576 mice under control conditions. *p < 0.05 versus WT (D) Quantification of 4-AP-induced epileptiform activity, as frequency (Hz), interval (sec), and amplitude (mV), in the presence of 100 μM anisomycin, in acute hippocampal slices of 3-month-old WT and Tg2576 mice. Values are expressed as a percentage of basal values measured in the presence of 4-AP alone before starting the perfusion with anisomycin. *p < 0.05 versus WT.
