| Summary: | Electroencephalograph (EEG) has been widely used in brain wave mapping studies with several subject conditions, such as in evaluations of dementia and encephalopathy, screening for possible epileptic spikes, investigational for clinical use in mental disorders. In addition, the EEG has also been used to investigate the response of human brain in listening to music, movement of arm, and turning of neck. In this study, electroencephalograph was used to study the eye response to the blinking light. Brain waves recorded during the subject watching 20 Hz flickering light by using wireless electroencephalograph 14 channels. By recording the brain waves of the subject in the “Edf’s” format, the electroencephalogram was then analyzed using tools such as channel spectra and maps, centering, filtering, and Welch’s power spectral density estimation. Using Power Spectra Density (PSD) graph, we can estimate the active part of the lobe as eye responds to flickering light, i.e. right Parietal lobe, both side of Occipital lobe and left Frontal lobe. |
