First, the popular approach of focusing on the effect estimate β0 associated with the first basis (canonical) function through the hypothesis (6b) was adopted (Figure 2A bottom). Secondly, the L2D approach (7) was used on the first two basis functions (not shown here) as well as all three. Thirdly, MVT was performed using (2b) with the three coefficients. Lastly, the HDR curve at each condition was reassembled for each subject using the three coefficients, and the reconstructed effect estimates only at the first 10 TRs were analyzed with 3dMVM for two reasons: a) with the three SPM curves covering 32 s or 25 TRs, the model would contain too many parameters relative to the data size; b) the effect estimates after the first 10 TRs were mostly negligible. Two tests, XUV and AUC, were performed while MVT and XMV were impossible because the rank was 3 among the 10 effect estimates from the linearly reconstructed HDR per condition.","tracks":[]}
