SUIT Cerebellar Lobular Atlas

Returns the SUIT cerebellar parcellation (Diedrichsen et al., 2009): the cerebellar cortex split into anatomical lobules plus the deep nuclei (dentate, interposed, fastigial).

Usage

suit()

Value

A ggseg_atlas object with components:

atlas

Character. Atlas name ("suit")

type

Character. Atlas type ("cerebellar")

palette

Named character vector of colours for each region

data

A ggseg_data_cerebellar object containing:

geom

A brain_polygons table for 2D rendering

vertices

Vertex indices for surface lobules

meshes

Per-structure 3D meshes for the deep nuclei

Details

Surface lobules carry vertex indices into the shared SUIT cerebellar mesh (see get_cerebellar_mesh()); deep nuclei carry individual 3D meshes. The 2D geometry is stored in the sf-optional polygon (geom) representation, so the atlas renders with ggseg without requiring sf installed.
