Effects of Small Ethanol Doses on the Auditory Evoked Transient and Sustained Potentials in the Human Eeg
The effects of ethanol on the central nervous system are reflected in the background EEG rhythms as well as in evoked electrical activity of the brain (for a review, see Begleiter and Platz, 1972). At present, however, it is not clear whether ethanol acts directly on the nervous tissue whose activity underlies the EEG recorded from the scalp (see Kalant, 1975). This is especially true when large ethanol doses are used, since several indirect mechanisms of action are possible which are associated with the general state of intoxication. Therefore, it is of interest to examine the effects of ethanol on the electrical activity of the brain when sufficiently low doses of ethanol are used to avoid producing behavioral signs of intoxication.
