Sampling rate dependence of correlation at long time lags in BOLD fMRI measurements on humans and gel phantoms
The aim of this study is to investigate the effects of sampling rate on Hurst exponents derived from Blood Oxygenation Level Dependent functional Magnetic Resonanse Imaging (BOLD fMRI) resting state time series. fMRI measurements were performed on 2 human subjects and a selection of gel phantoms.
