Abstract

Recently, the issues related in poor concentration are emerging because of the environment which has become the over-development of the left brain. It raises many problems like a serious ailment ADHD as well as a learning disabilities.
In this study, we aim to find the relationship between EEG and concentrativeness by measuring the brain waves from the subjects who are focusing on performing the visual stimulus tasks in short term. Among the brain waves, we targeted mainly the beta-wave which primarily occurs in concentrating and analyzed Low-Beta(12~15Hz) and Mid-Beta(15~20Hz) especially. Therefore the experimental results are represented by visual stimulus tasks and location of electrodes respectively.

Key words : EEG, Brain wave, Concentrativeness, Beta Frequency
