Simple Regression: Recapitulation
¥ Choose HRF model h(t) [AKA fixed-model regression]
¥ Build model responses rn(t) to each stimulus class
H Using h(t) and the stimulus timing
¥ Choose baseline model time series
H Constant + linear + quadratic + movement?
¥ Assemble model and baseline time series into the columns of the R matrix
¥ For each voxel time series z, solve zÈRb for
¥ Individual subject maps: Test the coefficients in that you care about for statistical significance
¥ Group maps: Transform the coefficients in    that you care about to Talairach space, and perform statistics on these    values
