(H) Line graph showing the average value of the synaptic phospho/total ratio of eEF2 at various time points after DHPG and NMDA treatment until 5 minutes of recovery. Data presented as mean +/- SEM, **p<0.01. Values in all other groups were normalized to the 0 min group for the corresponding experiment and all the data points are represented as a fraction of the initial time point. ***p<0.001, ****p<0.0001, n≥ 5 animals per group.
