Package 'ggsegAAL'

Title: AAL Atlases for the 'ggsegverse' Ecosystem
Description: AAL (Automated Anatomical Labeling) atlases for the 'ggseg' ecosystem. Provides unified 'ggseg_atlas' objects for AAL2 (cortical, Rolls et al. 2015) and AAL3 (cortical, subcortical, cerebellum, Rolls et al. 2020), with both 2D polygon geometry and 3D vertex/mesh data for use with 'ggseg' and 'ggseg3d'.

AAL Cortical Atlas

Description

Brain atlas for the original Automated Anatomical Labeling parcellation (Tzourio-Mazoyer et al. 2002).

Usage

aal()

Value

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

AAL2 Cortical Atlas

Description

Brain atlas for the AAL2 parcellation (Rolls et al. 2015) with 41 cortical regions per hemisphere. Contains both 2D polygon geometry for ggseg::geom_brain() and 3D vertex indices for ggseg3d::ggseg3d().

Usage

aal2()

Details

Region names confirmed by Herve Lemaitre (AAL2 co-author), mapping the original generic annotation labels to anatomical AAL2 names.

Value

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

AAL3 Cerebellum Atlas

Description

Cerebellar parcellation from AAL3 (Rolls et al. 2020) with 17 regions including bilateral lobules and midline vermis. Contains both 2D polygon geometry for ggseg::geom_brain() and 3D meshes for ggseg3d::ggseg3d().

Usage

aal3_cerebellum()

Value

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