¥ Instead of inputting a signal model time series (e.g., created with waver
and stimulus timing), you input the stimulus
timing directly
H Format: a
text file with 0s and 1s, 0 at TR-grid times with no
stimulus, 1 at time with stimulus
¥ Must specify the maximum lag (in units of TR) that we expect HRF to last after each stimulus
H This
requires you to make a judgment about the activation
Ñ brief or long?
¥ 3dDeconvolve returns estimated
values for each bq for each
stimulus class
H Usually
then use a GLT to test the HRF (or pieces of it)
for significance
