| Research Abstract |
The present study investigated responses of electroencephalogram to exposure of stresses, performing aerobic exercise and resting without task. The observations obtained include the following. (1) The alpha wave in the lower-frequency band (8-10Hz; low-alpha wave) was significantly reduced by 20 % in amplitude during performing a mental arithmetic and listening to unpleasant sound. The odor of peppermint elicited the alpha wave in the higher-frequency band (10-13Hz). (2) The amplitude of the lower-alpha wave was increased by 20 % with reference to the pre-stressed alpha wave by performing aerobic exercise or resting for 30 min after the tasks of the mental arithmetic and unpleasant sound. Statistical significance between the exercise and resting was not found, but the amplitude-increasing rate of the low-alpha wave was larger in the exercise. The results suggests the possibility of understanding human stressed states by means of the electroencephalogram such as the alpha wave.
