Binaural Beat Entrainment Effect on Prefrontal and Parietal Brain EEG in Theta Frequency

摘要

In this age of distraction, achieving focus is a very difficult task. Yet focus in an important prerequisite before we begin any learning process. When brain focuses, brain changes its state from beta dominant frequency state to theta dominant frequency state. One can achieve focus state by practicing meditation. However, meditation training takes a lot of time and effort. Mindec developed Teknologi Minda Pintar binaural beat audiophone to help one's brain achieving theta state quicker. In this paper, we showed how effective the brainwave changes from twenty five subjects under 30 minutes exposure to Teknologi Minda Pintar audiophone. Brain EEG analysis is focused on parietal and prefrontal cortex which are vital in learning process. We employed Event Related Synchronization (ERS) method to get the index of the brainwave response to the binaural beat stimuli. The results showed that brainwave frequency shifted toward the Theta state, with the most statistically significant entrainment detected on lead Pz.
