The abstracts presents a study of the Hurst exponent of fMRI BOLD time-series acquired at different sampling rates (TR). The Hurst exponent is related to the spectral characteristics of a time-series, and the change in the Hurst exponent value at different TRs due to frequency aliasing is demonstrated.
