사고 활동 중의 전방전두엽에서의뇌전도 분석에 기초한 두뇌의 활성화 상태 분석

Abstract

This study discussed the brain functions by analyzing the EEG measured in the prefrontal lobe of the learners who are at the first year high school when they are in the process of thinking, trying to solve the problems of a numerical progression, vocabulary, perception of space and scientific thinking which are given to them for analysis purpose, or when they are sunk in meditation.When the learners were in meditation state, the activity of α wave rose highly and that of β wave fell low amid the most active θ waves. However, when they were in the process of thinking those four types of problems both θ and β waves tended to become increasingly active. The results of this study mean that the activities of solving a numerical progression or vocabulary problems made the left brain predominantly active while problems involving perception of space and scientific thinking made the right brain to have predominance. It is therefore reasonable to think that the differentiation of the left and right brain functions would take place before they reached the age of the first year high school in view of the results of the other study regarding the differentiation of the brain functions conducted on the middle school students.And our findings that activities involving the perception of space and the solving of scientific thinking problems made the right brain's θ and β waves predominantly active imply that this wavelength range is closely related to the learner's creativity.
