Dear SPM users,
I use SPM for analysing a MRI working memory task in subjects with AD and I
am wondering, if someone can help with choosing a cut-off period for this
task / box-car design with three different conditions. Each condition takes
30 sec, TR of 3 sec, task-duration 10 minutes.
The design: Rest (a) zero back condition (b) for 5 minutes; Rest (a) one
back condition (c) for 5 minutes)
a b a b a b a b a b a c a c a c a c a c
Or does anyone have an even better idea for analysing this set of data? For
example to split it into two separate sessions?
Thanks a lot in advance,
Martina
