Human Attention and Electroencephalograms

MATLAB is an advanced numerical calculation tool that is widely used by engineers and scientists. MATLAB is popular in such fields as image processing, signal processing, communications, and automation systems. MATLAB efficiently reflects changes in research results. The use of the electroencephalogram (EEG) is an important method for exploring human brain activity. It provides useful evaluation data about the changeability of the EEG frequency band. By simplifying the programming environment and improving the EEG results, EEG-MATLAB coding was developed in this study. Ten recordings of subjects were performed using EEGs. The EEG features were compared under two conditions: relax and un-relax. For statistical analysis, a correlation coefficient was used to correlate the two sessions with EEG-extracted features. The objective of this study was to help researchers in EEG analysis to run the code and compare the EEG bands: delta (up to 4-Hz), theta (4–8-Hz), alpha (8–15-Hz), beta (15–32-Hz), and gamma (≥ 32-Hz) waves. The results of this study can also be used for any analysis that employs EEGs in mental status research.
