Figure 3. VEP amplitude changes after pharmacological infusion of drugs in V1.

Figure 3

Effects of scopolamine (B, Sco+CCh), CPP (C, CPP+CCh), mecamylamine (D, Mec+CCh) or MLA (E, MLA+CCh) infusion prior to CCh administration are shown compared to aCSF+CCh injected animals as control group (black histograms). The long term enhancement of VEP amplitude is abolished in an identical manner by scopolamine, CPP and mecamylamine, suggesting that mAChR and nAChR could act upstream of NMDAR intracellular pathways. Drug infusion time points are indicated by black arrows.
