Effects of the letter string type and alcohol intoxication on scalp ERPs at Cz. Panel a): grand average ERP waveforms to the four letter strings under placebo. NN do not evoke the N400, with peak latency of 296 ms. In contrast, the PN evoke the largest N400 amplitude. Panel B: grand average waveforms obtained under alcohol and placebo are superimposed for the four conditions. Panel C: bar graphs of the N400 peak amplitudes elicited by the RW, AW, and PN conditions show that alcohol increases the N400 amplitude to AW and marginally to RW only. Shading of the bar graphs corresponds to the lines in a). Alcohol and placebo bars for each condition are positioned on the left and right respectively. Negative is up.
