摘要：
PROBLEM TO BE SOLVED: To establish technology that evaluates and analyzes a brain wave function in real time.SOLUTION: A method is provided for evaluating and reading intracerebral expression information in real time from a brain wave containing a transient frequency component without adding average addition processing. The method includes: a step of previously recording typical electroencephalogram waveform data of the same category as an evaluation object brain wave, and performing wavelet correlation analysis to compile it into a database； and a step of performing the wavelet correlation analysis by adding one of the newly measured unknown electroencephalographic waveform of an evaluation subject (hereinafter called as, "target electroencephalographic waveform") on the database, and deciding and evaluating in real time the intracerebral expression information represented by the typical electroencephalogram waveform showing the highest coefficient of correlation with the new target electroencephalographic waveform to consider it to be the intracerebral expression information represented by the target electroencephalographic waveform as a single shot response.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】リアルタイムでの脳波機能評価・解析する技術を確立する【解決手段】一過性の周波数成分を含む脳波から平均加算処理を加えずに、脳内表現情報をリアルタイムで評価・読み出す方法であって、評価対象脳波と同一カテゴリーの典型脳波波形データを事前に記録し、wavelet相関解析してデータベース化するステップと、前記データベース上で評価対象者の未知の新たに測定された脳波波形(以下、「対象脳波波形」)を１つ加えてwavelet相関解析を行い、新たな対象脳波波形と最も高い相関係数を示した典型脳波波形が表す脳内表現情報を、その単発応答としての対象脳波波形の表す脳内表現情報とリアルタイムで判断・評価するステップとを備える方法。【選択図】図１
