Abstract
The amplitude power spectra and fractal dimensions of surrogate data designed as coloured noise were compared with spectra and FDs of biosignals in order to improve the tools for brain activity analysis. It is interesting if biosignals yielded spectral indices and fractal dimension values different from almost all of those of surrogate data, could we have more confidence that original biosignals (brain activities) arised from a nonlinear process.
