| 摘 要： | 基于ERP技术,比较了一系列的平面和立体图片刺激的脑电信号。通过分析比较平面和立体图片的脑电信号,发现立体图像诱发的P300成分波幅比平面图像的P300成分波幅大。在非注意条件下,与平面相比,立体图像诱发的N140成分潜伏期较长。注意刺激图片诱发总能量均比非注意刺激图片产生的能量大。

| Abstract: | A series of 2D and 3D images' electroencephalography(EEG) using ERP technology were compared.By analyzing EEG signal of 2D and 3D image,it was found that amplitude of P300 component evoked by 3D images is higher than that by 2D images.Especially,in the unattended condition,the N140 component evoked by 3D images has a long latency.Paying attention to stimulus will evoke more EEG energy than that of paying no attention. |
