先前研究指出,伴隨性負電位變化(Contingent negative variation,CNV)之振幅,對於個體的心理狀態是有效的量測指標。故本研究將利用低溫超導量子干涉元件(Superconducting Quantum Interference Device,SQUID)組成之128通道腦磁圖儀(Magnetoencephalography,MEG)系統,來深入探討由情緒圖片刺激所造成人體放鬆狀態下的腦磁訊號。藉由觀察磁場的等位線分佈圖(magnetic isofield contour map)及電流密度(Current Density Reconstruction,CDR)推算腦磁訊號源的結果,來分析不同情緒圖片下所對應到大腦皮質層反應區域的差異。
受試者共五位身體健康符合實驗需求的受試者來參加實驗。本研究實驗設計採用情緒圖片來產生心理放鬆程度的不同,以進行腦磁波的量測。結果顯示左半腦運動區之CMV振幅大小會隨著圖片不愉快的程度增加而上升,雖然每位個體對於不同的情緒圖片刺激在CMV波幅上會產生有不一樣的活躍程度,但每一位受試者於觀看愉悅圖片時與不愉悅圖片時的CMV波幅在統計上有顯著差異,所以運動區之CMV振幅用來量測情緒狀態是非常有效的量測指標。
