The acute effect of low-dose alcohol on working memory during mental arithmetic: I. Behavioral measures and EEG theta band spectral characteristics
International Journal of Psychophysiology Volume 73, Issue 2, August 2009, Pages 133-137

Task-related EEG changes were studied during the performance of a mental arithmetic task, as influenced by low alcohol dosages with the presumption that even “social” drinking may have detrimental effect.

No detrimental alcohol effect was seen on behavioral indices of task performance. However, the ethanol-induced moderate reduction of the task-related frontally dominant theta increase, probably corresponding to working memory demand, is a modest but clear electrophysiological sign of alcohol effect in this low-dose range.
