¥ Can represent arbitrary shapes of the HRF, up and down, with ease
¥ Meaning of each bq is completely obvious
H Value of HRF at time lag q×TR after activation
¥ 3dDeconvolve is set up to deal with stick functions for representing HRF, so
using them is very easy
¥ What is
called p here is given by command line option -stim_maxlag in the program
¥ When
choosing p, rule is to estimate longest duration of neural
activation after stimulus onset, then add 10-12 seconds to
allow for slowness of hemodynamic response
