Pharmacological Mechanisms of Cortical Enhancement Induced by the Repetitive Pairing of Visual/Cholinergic Stimulation

A) Representative comparison of the power spectral densities (PSDs) of the pre- and post-training VEPs from the VS/HDB group as analyzed with the short-time Fourier transformation. B) Comparison of the PSDs in the 200–250 ms time window after the stimulus presentation. Only the VS/HDB group exhibited an increase in gamma band oscillations (†, one-way ANOVA, p < 0.05). Gamma (C) and beta band (D) power during VEP recording. There was an increase of beta (15–30 Hz) and gamma band (30–90 Hz) power 200–250 ms after stimulus onset.
