Dear experts of AFNI,
I am using AFNI to analyze fmri data where monkey were training to watch movies.
The design was simple, 2.5min resting (no visual stimuls, no rewards) --> 5 min movies watching (with regular rewards) --> 2.5min resting
In total of 10mins, and many runs were collected.
I want to use the data to locate regions that "deactivated" (lower averaged BOLD response for example) during the movies-watching, compared with the resting period.
Since the stimulus was very long (5min), it seems not suitable to use the BLOCK(300) basis function to model the regression.
Is there any better basis function or other methods to model very long stimuli like movies?
Thanks!
