I am wondering if the canonical HRF is the best model for the HRF considering the
variability associated with stimulus modalities, possible physiologic variability within the
brain and across individuals.
There are other options is SPM: Fourier Set, Gamma Functions and FIR.
Where can I learn about these options? What I would like to learn is:
What are appropriate submenu choices for these options?
What are the pros and cons of using these options?
My cursory understanding of these options is that they may be alternatives to the canonical
HRF if the investigator is not sure about the shape of the HRF.
