Multivariate PLS model peak activations, bootstrap ratios, and cluster sizes for regions showing increased BOLD signal variability with age.
| Region | Hem | MNI coordinates | BSR | Cluster size (voxels) | ||
|---|---|---|---|---|---|---|
| X | Y | Z | ||||
| Precentral gyrus | R | 48 | 8 | 44 | 4.87 | 49 |
| Precuneus | L | −4 | −64 | 32 | 4.86 | 167 |
| Anterior cingulate | L | 0 | 32 | 24 | 3.90 | 45 |
| Superior medial gyrus | L | 0 | 52 | 8 | 3.64 | 20 |
| Middle temporal gyrus | R | 56 | −48 | 12 | 3.61 | 18 |
| Middle occipital gyrus | L | −44 | −76 | 36 | 3.39 | 16 |
| Angular gyrus | L | −56 | −68 | 24 | 2.83 | 16 |
Note: SD = standard deviation; BOLD = blood oxygen level-dependent; Hem = hemisphere; MNI = Montreal Neurological Institute; BSR = bootstrap ratio (model salience/bootstrapped standard error).
