The brain-based MRI lie detection experiment methodology is reviewed for the first time, including the magnetic resonance imaging paradigm,the double-block deign,the equidistance hit-ball and the test mechanice,This paper illustrates the research results of 3D MRI lie detection and the contrastive experiment of otopoint mapping brain signature lie detection,ingeminates the lie-Truth Law(PT/PL ≤0.618)which we get from the statistic of the world MRI reports. The conclusion points out the essence of this technology,its advantages and disadvantages,and the evolution of this methodology. 相似文献

利用心理旋转现象刺激大脑做连续的认知加工,基于小波分析等时距间接测量脑神经递质的涨落,由10级小波系数谱构造出时域特征曲线作为测量结果.研究发现认知能耗的脑神经递质的表征特点是:时域曲线都呈现主峰连副峰再拖尾;主峰的斜率反比(面积正比)于(成人)年龄;副峰的出现预示着疲劳的开始.结论是认知疲劳可测而且相应的认知能耗小波模型具有普适性和特异性. 相似文献
