At the beginning of the block of 100 words, the subject heard an introductory sentence. Half of the words completed the sentence well and the other half did not. The subject pressed a reaction key immediately after hearing a proper word. After the control condition, the subject ingested alcohol (1 ml/kg). Alcohol attenuated the amplitude of NI00 to both Finnish and English words, this attenuation being significantly stronger for English than for Finnish words. The early differential effect of alcohol suggests that language-specific information is extracted in the cortex already approximately 100 ms from the word onset. The results are in line with animal experiments demonstrating that alcohol selectively affects the activity of single units involved in newer forms of behavior.

One charmed particle with x F > 0 is fully reconstructed and the other is at least partially recontructed. The distributions of and p 2 T are compared with a next-to-leading order QCD calculation.
