✦ Synopsis

Spontaneous (EEG) and visual evoked (V.E.P.) electroencephalographic activity have been longitudinally studied during acute alcohol poisoning in 8 young voluntary subjects; a comparison with i) neuropsychiatric state of the subject, ii) alcoholic haematic rate and iii) the time of reaction to different sensorial and sensitive stimulations has been made.

A spectral EEG analysis has been carried out and the temporal behaviour of four main frequency bands has been studied.

1. The V.E.P. can show alterations both in the latency and amplitude of its components as well as in morphology; such effects may alter from subject to subject.

2. EEG alterations are as follows: a) a constant slacking of alpha rhythm (about 1 c/s) occurs, which is parallel to its amount reduction.

b) a new slow activity is always verified. Band analysis shows that it can belong to every value under the alphfa frequency, namely to the 0--3.2 c/s band.

3. EEG alterations are not time]y corr]ated, either with neuropsychiatric changes or the alcohol hematic level
