Nicotine improved visual attention upon daily exposures, similar to the electrophysiological alterations. (a) Visual attention accuracy throughout the daily regimen of 0.2 mg/kg nicotine, as measured by the percentage of correct cued responses. Asterisks indicate t-test significant nicotine vs saline differences. (b) Data from the nicotine-exposed rats highlighting that the visual attention improvement (left) paralleled the low gamma potentiation (right), also shown in Figure 2. # indicates within-session effects.
