Returns the Desikan-Killiany cortical parcellation atlas with 34 regions per hemisphere (68 total) on the cortical surface.
dk()A ggseg_atlas object with components:
Character. Atlas name ("dk")
Character. Atlas type ("cortical")
Named character vector of colours for each region
A ggseg_data_cortical object containing:
Data frame with label and vertices columns
Simple features data frame for 2D rendering
The atlas contains 34 regions per hemisphere including: banks of superior temporal sulcus, caudal anterior cingulate, caudal middle frontal, cuneus, entorhinal, fusiform, inferior parietal, inferior temporal, isthmus cingulate, lateral occipital, lateral orbitofrontal, lingual, medial orbitofrontal, middle temporal, parahippocampal, paracentral, pars opercularis, pars orbitalis, pars triangularis, pericalcarine, postcentral, posterior cingulate, precentral, precuneus, rostral anterior cingulate, rostral middle frontal, superior frontal, superior parietal, superior temporal, supramarginal, frontal pole, temporal pole, transverse temporal, and insula.
This atlas is based on the FreeSurfer aparc annotation and is one of the
most widely used cortical parcellations in neuroimaging research.
The atlas works with both ggseg (2D polygon plots) and ggseg3d (3D mesh visualizations) from a single object.
