Description
これは具体的には、パターンアピアランス刺激及びパターンリバーサル刺激と呼ばれるものである。
磁気シールド空間内に配置された脳磁計を有するとともに、この脳磁計を構成するヘルメットに被験者の頭部を挿入し、前記被験者に視覚刺激を与えて誘発脳磁場を測定する視覚誘発脳磁場計測システムにおいて、前記脳磁計の前記ヘルメットが配置された上側面に反射板及びスクリーンを収納し、視覚刺激検査に際しては、前記反射板とスクリーンを所定位置まで移動させることを特徴とする。
前記反射板およびスクリーンは視覚刺激検査終了後は元の位置に戻され、カバーで覆われるように構成したことを特徴とする。
図1(a)において、11は脳磁計であり、図2に示す従来例の脳磁計1とはヘルメット1aの上部側面に矩形状の穴11aを設けた点のみが異なり機能は同一である。
従って本発明は、上記実施例に限定されることなく、その本質から逸脱しない範囲で更に多くの変更、変形を含むものである。
