Dear all,

Updated: I noticed that "atlas.info" already describes "Cerebellar parcelation from AAL Atlas (26 ROIs)" with the reference: Automated Anatomical Labeling of Activations in SPM Using a Macroscopic Anatomical Parcellation of the MNI MRI Single-Subject Brain. N. Tzourio-Mazoyer, B. Landeau, D. Papathanassiou, F. Crivello, O. Étard, N. Delcroix, B. Mazoyer, and M. Joliot. NeuroImage 2002. 15 :273-289. I have no question now.

According to my knowledge, the default atlas is the Harvard-Oxford atlas, which doesn't include the cerebellar ROIs. However, I noticed that the default atlas (\conn\rois\atlas.nii) includes the following ROIs:
Cereb1 l (Cerebelum Crus1 Left)
Cereb1 r (Cerebelum Crus1 Right)
Cereb2 l (Cerebelum Crus2 Left)
Cereb2 r (Cerebelum Crus2 Right)
Cereb3 l (Cerebelum 3 Left)
Cereb3 r (Cerebelum 3 Right)
Cereb45 l (Cerebelum 4 5 Left)
Cereb45 r (Cerebelum 4 5 Right)
Cereb6 l (Cerebelum 6 Left)
Cereb6 r (Cerebelum 6 Right)
Cereb7 l (Cerebelum 7b Left)
Cereb7 r (Cerebelum 7b Right)
Cereb8 l (Cerebelum 8 Left)
Cereb8 r (Cerebelum 8 Right)
Cereb9 l (Cerebelum 9 Left)
Cereb9 r (Cerebelum 9 Right)
Cereb10 l (Cerebelum 10 Left)
Cereb10 r (Cerebelum 10 Right)
Ver12 (Vermis 1 2)
Ver3 (Vermis 3)
Ver45 (Vermis 4 5)
Ver6 (Vermis 6)
Ver7 (Vermis 7)
Ver8 (Vermis 8)
Ver9 (Vermis 9)
Ver10 (Vermis 10)

They look like the cerebellar ROIs from the AAL3 atlas.

Is the default atlas a combination of the HOA atlas (cortical and subcortical regions) and the AAL3 atlas (cerebellar ROIs)?

Best regards,
