Comparison between the Left and the Right Brainwaves for Delta and Theta Frequency Band after Horizontal Rotation Intervention

This paper investigates the difference between the left and the right brainwaves for delta and theta frequency band after horizontal rotation (HR) intervention using electroencephalography (EEG). The EEG signals were captured from the samples before and after under-going HR. The artifact of the EEG signals was removed automatically by means of a program designed to eliminate data above 100 micro volts. Then the Power Spectral Density (PSD) was applied to the artifact removed data and comparison was carried out to determine the better method and the effects of HR intervention. MATLAB and Paired T-test analysis from SPSS was used and graphs were plotted to show the correlation between the left and right brainwave before and after HR involvement. In conclusion, by applying PSD to the artifact removed signals, results improved significantly. It also shows that the correlation of the left and the right brainwaves had improved for delta and theta frequency bands after HR.
