On the Distinguishability of HRF Models in fMRI

Modelling the Haemodynamic Response Function (HRF) is a critical step in fMRI studies of brain activity, and it is often desirable to estimate HRF parameters with physiological interpretability. A biophysically informed model of the HRF can be described by a nonlinear time-invariant dynamic system....
