EEG Brainmapping Analysis of Mental Arithmetic Task Performed by Drug Convicts

Drug convicts are thought to have decreased performance of the brain to think, concentrate, and carry out logical functions. To monitor how the drug could affect the human brain, mental arithmetic is performed, and the EEG signals are recorded. In this study, addition task performance men show that some subjects have different counting accuracy. Mental arithmetic was monitored by International 10/20 system EEG with 19 scalp electrodes. The raw EEG data was processed and plotted to 2d mapping based on the power spectrum. The spectrum changes seen in Brain mapping, show how the mental arithmetic process takes place. The results of brain mapping can be a parameter that indicates the calculation process so that it can show the quality of the brain's work. Independent component label classifier performed, subject 7 obtain 79,8%, subject12 obtain 94,3%, subject15 obtain 92,3% accuracy as brain label.
