¥Data Processing
HIRF for each of the 4
stimuli were obtained using 3dDeconvolve
HRegressor coefficients
(IRFs) were normalized to percent signal change (using 3dcalc)
HAn average activation
measure was obtained by averaging IRF amplitude from the 4th through
the 10th second of the response
åCapturing the positive
blood-oxygenation level dependent response but not any post-stimulus
undershoot.
åThese activation measures
will be the measurements in the ANOVA2 table.
HAn 3dANOVA2 was carried out with:
åFactor A, fixed: HM,
TM, HP, TP (the 4 types of stimuli)
åFactor B, random: 9
subjects
