摘要
人类所具有无限的认知能力 ,是一个远未理解的难题 ,现尚缺乏生理学数据。将立体视觉与认知结合 ,采用电生理方法 ,研究大脑对外部刺激产生的认知响应。通过研究者作为部分受试者参与实验的全过程 ,感受外部刺激产生完整认知响应的细节 ,切身感受形成稳定的认识知具有鲁棒性。结果表明 ,认知是一个多因素动态过程 ;用单因素诱发 ,获得高级视皮层认知特征响应新的N2波 。
Human being's infinite cognitive ability is a far unsolved poser largely due to the shortage of physiological data. By linking stereopsis and cognition the cognitive response to external stimuli using the electrophysiological method is studied. Investigators directly took part in the entire experimental processes as volunteers. They were able to experience the details of complete cognitive response produced by external stimuli and sense the formation of stable cognition with robustness through personal understanding. Results show that cognition is a dynamic process of multiple factors. In particular, a new N2 waveform of cognitive characteristics is found to respond to a single stimulus at the visual cortex of high level. This N2 waveform is also verified by computing its nonlinear complexity.
