The effect of pretreatment, treatment, and pretreatment + treatment with Vinpocetine (Vin) on excitatory postsynaptic potential (EPSP) slope in the dentate gyrus (DG) utilizing 400 Hz tetanization of the AD-induced rats. Long-term potentiation (LTP) of the EPSP slope in DG granular cell synapses is meaningfully dissimilar between groups. Values are represented as the mean ± SEM% of the baseline. *: P < 0.05 compared to the control group and $: P < 0.05 compared to the AD group
