Abstract :
A time series from a human electroencephalogram (EEG) is used as a local perturbation to a chemical reaction-diffusion model exhibiting spatio-temporal chaos. For certain finite ranges of amplitude and frequency it is observed that the strongly irregular EEG perturbations can induce transient coherence in the chaotic system. This could be interpreted as “on-line” detection of an inherently correlated pattern embedded in the EEG
