In the past, in study of the evoked brain wave, the averaging was the most general method for analysis of signal components in brain wave. Specially, the averaging was applied for several evoked brain waves on the process of recognition to the stimulation, i.e. P300. However, any information for the averaging. The averaging is difficult to evaluate the evoked brain wave because of it’s characteristics. In this study, it was the purpose to reveal the frequency range, the latency and the acyive parts of brain by following two method. 1) frequency and statistic analysis of evoked brain wave 2) measurement of temperature distribution on the surface of the head. The experiment for the measurement of the evoked brain wave was applied to fifteen men whose age were from 22 to 25. After frequency and statistic analysis, and waves were obtained at about 300ms latency. This result is as same as the averaging’s result. From the temperature measurement, it was considered that the recognition to the stimulation was performed at the parietal lobe.
