Figure 4. Treatment with memantine partially restores the LTP deficit after rmTBI.
(A) The LTP responses induced by HFS in M1 slices. LTP magnitude (fEPSP slope change 30min after HFS relative to baseline) was attenuated in the vehicle treated mice (Veh: 110.4 ± 0.8% of baseline; n=9, p<0.001) as compared to sham (183.6 ± 1.7% of baseline; n=8, p<0.001). In the memantine (MEM) treated group, this LTP deficit was partially recovered (132.6 ± 2.4% of baseline; n=7, p<0.001). (B) Statistic analysis of the fEPSP slopes changes averaged from the last 10-min’s (45–55min) recording of each group [F(2,30)=786.3, p<0.001 by one-way ANOVA]: ***p<0.001 indicates post hoc test between two means as indicated in the graph. ###p<0.001 indicates paired t-test between fESPS slope changes and individual baseline (initial 10-min’s recording). n = 8/group
