Abstract Previous research has suggested a possible link between the effects of scopolamine-induced muscarinic cholinergic receptor blockade on memory and its effect on auditory P3 amplitude and latency. A potential problem with this hypothesis is that, although scopolamine has been reported to increase P3 latency in both visual and auditory modalities, amplitude reductions have been reported only in the case of auditory P3 at Cz. In the present study, subjects were injected intravenously with 5.7 μg/kg of scopolamine or saline in a double blind design. A significant reduction in verbal recognition memory performance was observed. This memory impairment was shown to be largely specific to the encoding of verbal material. The drug effect was of equal magnitude when words of either high or low word frequency were used. Auditory P3 was recorded from frontal central and parietal sites along the midline and over left and right hemispheres. In contrast to a number of earlier reports using a similar drug dose, o...
