MarsAtlas

Cortical parcellation model

MarsAtlas is a model of cortical parcellation. It can be applied to any cortical surface via the HipHop parameterization pipeline, available in the BrainVisa Cortical Surface Toolbox, under the Anatomy category.

MarsAtlas has been developed in collaboration with Andréa Brovelli at INT.

It has been primarily designed for functional data analysis and localization. Both the atlas and its use for functional analysis have been presented int he following paper:

Guillaume Auzias*, Olivier Coulon*, Andrea Brovelli (2016) MarsAtlas : A cortical parcellation atlas for functional mapping, Human Brain Mapping 37(4), p. 1573-1592, url, doi:10.1002/hbm.23121 (* equal contribution)

It has also been used for functional connectivity inference in the following paper:

Brovelli, A., Badier, J.-M., Bonini, F., Bartolomei, F., Coulon*, O., & Auzias*, G. (2016). Dynamic reconfiguration of visuomotor-related functional connectivity networks. Journal of Neuroscience. https://doi.org/10.1523/JNEUROSCI.1672-16.2016 (*equal contribution)

The atlas is as shown below on the HipHop138 template.

It contains 41 parcellation areas on each hemisphere. These labels are available via one texture per hemisphere, that are outputs of the HIP-HOP pipeline, in <subject>/t1mri/default_acquisition/default_analysis/segmentation/mesh/surface_analysis/<subject>_L/Rwhite_parcels_marsAtlas.gii.

The surface parcellation can be propagated to the cortical volume segmentation by using the  ‘Cortical Surface -> Low Level -> 2D parcellation to 3D parcellation‘ BrainVisa process. This should result in something like this:

Visualization: when looking at a subject’s parcellation (surface or volume) with Anatomist, the best colormap is ‘MarsAtlas’. From Brainvisa, there is a viewer in the HipHop pipeline, also accessible directly in ‘Cortical Surface -> Viewers‘, that does the job for you.

 

Below is a table with the nomenclature of parcellation labels.
