• Electroencephalograms (EEGs) were recorded from eight healthy university students and two healthy high school sutents using a 24-ch portable EEG system according to 10-20 international electrode placement system. The records were obtained 1) in relaxed resting condition; 2) while simple arithmetic calculations, "Hyaku-masu Keisann"; 3) keying e-mail on cell-phone keypad; or 4) reading a book. Data were analyzed by FFT, and we obtained the absolute content and the percentage content of six frequency components (delta, theta, alpha-1, alpha-2, beta-1. Beta-2) for the records from Fp1, Fp2, F3, F4, P3 P4, O1 and O2 electrodes. The relation between the occurrence of various EEG frequency components and light assignments has been studied. Some differences have been noticed among Eegs of adults and teenagers.
