Average breath-hold fMRI group maps from the standard delay (left) and subject-wise delay (right) analyses for young controls (top), old controls (middle), and patients (bottom) overlaid on MNI 152 template. Functional data shown at p < 0.05 with a minimum cluster size of 60 voxels. 11 of the 22 stroke maps were flipped so that all lesioned hemispheres were on the left side (displayed to the right in this figure).
