The influence of alcohol on the appearance of frontal midline theta activity

In 30 healthy male students aged 19 to 28 years of a mean age of 22.6 years, a study was made of the amount of Fm theta by recording EEG patterns from Fz by monopolar lead during the Uchida-Kraepelin serial addition task of a five-minute duration, before and after taking 1.5 ml of 43% whisky per Kg. At the same time, a determination was made of the blood concentration of alcohol, along with the MPI test in all subjects, to examine the relationship between the results obtained and the occurrence of Fm theta. The amount of Fm theta was significantly increased following drinking.
