Transcript levels of the genes associated with loss of synaptic plasticity (Bdnf, Syn, GluN1, α7-nAChR, and M<sub>1</sub>-mAChR), formation of neurofibrillary tangles (Tau4 and Tau3), and amyloid plaques (App, Adam10, and Bace1), in the hippocampus of rats at 0, 1, 3, 6, and 9 days after ODX (D<sub>0</sub>, D<sub>1</sub>, D<sub>3</sub>, D<sub>6</sub> and D<sub>9</sub>, respectively) were determined.
