Abstract

Initiated from the availability of a simple to use and portable wireless electroencephalography, an effort was taken to find out the hemisphere of the brain that would be more active during human physical body movements. By recording the human brain waves using this wireless headset, the electroencephalogram (EEG) data were then processed with EEGLAB, which is an interactive Matlab toolbox. Visual inspections were performed from the output of Channel Spectra and Maps. Data output from the power spectral density estimation from Matlab were tabulated using Microsoft Excel. The more active brain hemisphere results from the visual inspections and tabulated data were either crisscross, no crisscross or dominant regardless of the movement of the arm or leg raising and neck turning.
