¥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
