Can we say a duration of 1.7 s HRF convolvement is a delta function or boxcar?
I don't really see the importance of such terminologies, but some
reviewers do. In another occasion I checked the differences between
various HRF lengths and could see that unless we arrive at 10s stimuli
all the lower lengths are similar to delta.

Can someone illuminate the issue?
Best to all.
