Complex reaction time and EEG characteristics in alcoholics

In a group of 88 male alcoholics a psychodiagnostic electronic series CRD test (Complex Reactiometer Drenovac) was applied and electroencephalograms (EEG) were recorded. Results showed a relationship between the frequency of the basic rhythm in the EEG finding and rapid, accurate reactions at the CRD 4-A test. A positive relationship was also found between the satisfactory blocking of the basic rhythm by eye opening and faster and more accurate reactions at the same test.
