Dear SPMers,
I have a PET study that includes 17 Alzheimer`s desease patients (one
scan each subject). If I want to examine cerebral areas where glucose goes
down in relation to the decreasing of the MMSE in a "Single-subject:
covariates only" study, which contrast do you choose? -1 or +1 ?
Thank you,
Michela
