Is it necessary to measure all brain regions for the assessment of PAF?
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 12
Abstract
From decades of research, electroencephalography (EEG) has been proved as a potential non-invasive medical technique to measure the electrophysiological activities of brain. Alpha is one of the most prominent frequency bands of EEG because of its applications in cognitive enhancement and biofeedback methods. 300 participants were included in the present study to investigate the relationships between their cognitive performance and Peak Alpha Frequency (PAF). Brain activity was recorded from all significant brain regions in 250 participants and only from occipital region in 50 participants. The aim of the present study was to ensure the brain region which is the most dominant one to measure PAF/ IAF. Power Spectrum Density (PSD) method was used for EEG signal analysis. Interrelationship among PAF, IAF and PAF of six individual electrode positions was also explored. Findings reveled that parieto- occipital electrode points are sufficient to assess one’s peak alpha frequency.
