Dear SPM masters,
I have an uneven design with one block of emotional faces and five
blocks of sensory-motor control. I want to know how amygdala
connectivity varies with the emotional faces. I expect amygdala
connectivity during the sensory motor control blocks to be the same as
during baseline.
What is the best way to do this using PPI? Should I a) model both the
sensory-motor control blocks and the emotional face block or b) just
model the emotional face block and leave the control blocks to the
implicit baseline or c) something rather.
Cheers,
Fredrik
