| Research Abstract |
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.
