Dear All
I wonder if someone could point me to a fMRI paper that used the SPM99
approach to measuring percent single change as defined by Stefan in a post
to the list:
http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind0011&L=spm&P=R14245&I=-3
"In SPM99, the usual approach to determine the % signal change of a given
effect is to plot its fitted response. Because the global mean was
scaled to 100, the height of an effect is the % signal change with
respect to the global mean intensity of the scaled images."
Many Thanks
-Bill
