<p>  Subjects were for 40 healthy individuals (25.3 ± 6.8 yrs). Each task was performed for 5-minutes under eye-close lying, eye-close sitting, and eye-open sitting. The measurement sites corresponded to the left and right frontal lobes in accordance with the International 10-20 System. The expression number that represents the components of α and β waves quantified every three seconds was determined for five minutes, and expression time, mean expression number, and rate of change were determined and statistically analyzed. The site where the expression time of α and β waves was five minutes was only the left frontal lobe in all of the subjects in the eye-open sitting. There was a significant difference (P<0.05) in the mean expression number of α and wave in the left and right frontal lobe between subjects in the eye-open sitting and those in the eye-close sitting. There was a significant difference (P<0.001) in the rate of change of α and β wave in the left frontal lobe between subjects in the eye-close lying and those in the eye-open sitting. Consideration, it is important to observe the time of expression of α and β waves when the eyes are not stimulated. The results that agree with physiological change, indicated the possibility of evaluating frontal lobe activity on the basis of the mean expression number and the rate of change of α and β waves.</p>
