Atlases

MNI structural ²¹, provides lobar regions. ROI summary from the MNI structural atlas, which contains large/lobar ROIs, which can serve as a quick overview/summary of the data. The cerebellum ROI was replaced by the cerebellum atlas from FSLatlas FNIRT.

Three vascular regions (ACA, MCA and PCA bilateral), also from Tatu et al. ²²

Three labeling vascular regions (LCA, RCA and PCA bilateral) from Tatu et al. ²² together with a WM mask.

FEAST-based regions (three vascular regions split into proximal, middle and distal regions, resulting in a total of 9 vascular regions). These are vascular regions from the FEAST PreDiva paper ²³. The original vascular territories from Tatu et al. ²² were divided into proximal, intermediate and distal territories based on their estimated arterial transit time (ATT) in this paper ²³. If we expect vascular pathology, we might see more or less effects in the proximal vs. distal vascular ROIs.

Harvard-Oxford cortical ROI²⁴. Note that the HO-atlas is initially probabilistic, here the CONN-toolbox version is used [ref]. This cortical parcellation by the Harvard-Oxford atlas is a standard, accepted, atlas in NeuroImaging. ROIs are small though, so if we do not find effects this could also be an SNR (translating into a statistical power) issue.

Harvard-Oxford subcortical ROIs (Subcortical parcellation by the Harvard-Oxford (HO) atlas, same as above) and the thalamus atlas (parcellation of the thalamus by its connectivity).
