Web1 jul. 2024 · Furthermore, a ground truth HRF with an initial dip component representing the picking up of the oxygen consumption in the BOLD signal was used in this simulation. fMRI time series were generated using this known HRF θ 0, which was obtained based on the superposition of the SPM canonical HRF with its time and dispersion derivatives … Webdef ddspmt (t): """ SPM canonical HRF dispersion derivative, values for time values `t` This is the canonical HRF dispersion derivative function as used in SPM. It is the numerical difference between the HRF sampled at time `t`, and values at `t` for another HRF shape with a small change in the peak dispersion parameter (``peak_disp`` in … gibson semi hollow body copy
