Consistency of human brain response in perception-action coupling

一致性定义为由相同的噪声输入信号反复驱动的非线性动力系统，从系统的不同初始条件开始，其响应输出的可重复性（Uchida et al. 2004）。人类大脑作为一个高维非线性动力系统，是否具有一致性的特征，目前还不清楚。因此，我们证明了第一个证据，即大脑对嘈杂视觉输入的反应，通过脑电图测量，显示出一致性的特征。我们推测，大脑反应的一致性在人脑的信息处理中起着功能性的作用。

Consistency is defined as the reproducibility of response outputs in a nonliear dynamical system driven repeatedly by an identical noisy input signal, starting from different initial conditions of the system (Uchida et al. 2004).It is not known whether the human brain, which is a high-dimensional nonlinear dynamical system, shows the characteristics of consistency. We therefore demonstrate the first evidence that brain responses to noisy visual inputs, measured by electroencephalography, show the characteristics of consistency. We speculate that the consistency of brain responses plays a functional role in information processing in the human brain.
