Abstract

The present work looks at computerized EEG analyses with FFT method of drug addicts, rehabilitations, and normal controls, with the aim of comparison and delineation of group characteristics. Examinations of 30 taped EEG recordings were performed: 10 subjects were current drug users, recent methadone treatment, and normal controls, respectively. Statistical analysis was performed for the relative frequency of wave bands. The higher average amplitude is obtained from the addiction subjects. In the comparison with the signals source, channels P3 provide slightly higher average amplitude than other channels for all of subjects.
