Harvard-Oxford Subcortical Atlas

Description

Subcortical segmentation from the Harvard-Oxford atlas distributed with FSL, drawn on a grey-brain anatomical context. Contains 2D polygon geometry for ggseg::geom_brain() and 3D mesh data for ggseg3d::ggseg3d().

Usage

ho_sub()

Value

Description

Cortical parcellation with 49 regions per hemisphere from the Harvard-Oxford Atlas 2.0 (HOA-2), based on 50 HCP subjects. Contains 2D polygon geometry for ggseg::geom_brain() and 3D vertex indices for ggseg3d::ggseg3d().

Usage

ho2_cort()

Value

A ggseg.formats::ggseg_atlas object (cortical).

Harvard-Oxford Atlas 2.0 Subcortical

Description

Subcortical segmentation with 23 structures from the Harvard-Oxford Atlas 2.0 (HOA-2), based on 100 HCP subjects: the deep grey structures, the brain-stem, and the cerebellum split into grey and white matter. Drawn in four views: two axial, one coronal and a left-hemisphere sagittal. Contains 2D polygon geometry for ggseg::geom_brain() and 3D mesh data for ggseg3d::ggseg3d().

Usage

ho2_sub()

Details

HOA-2 divides the cerebellum into cortex and white matter only, which is a tissue segmentation like the rest of the subcortical volume rather than a cerebellar parcellation, so it belongs to this atlas. For a parcellated cerebellum see the SUIT and Buckner atlases in ggsegCerebellum.

Value

A ggseg.formats::ggseg_atlas object (subcortical).
