Fig. 3: The architectonic similarity of the cortical and gray matter regions of selected brain atlases.
From: A genetically informed brain atlas for enhancing brain imaging genomics
We evaluate the similarity between brain atlases using adjusted mutual information (AMI) score. We plot the pairwise AMI scores for GIANT atlas and some other selected brain atlas within a cortical regions and b gray matter tissue. Darker color represents higher concordance between two atlases. We marked the AMI > 0.8 with “×” representing the “perfect alignments”. The GIANT atlas is highlighted using blue dashed lines. CPAC200: a whole brain fMRI atlas generated via spatially constrained spectral clustering; Desikan: an automated labeling system for subdividing the human cerebral cortex on MRI scans into gyral-based regions of interest; Hammersmith: an automatic segmentation of young children’s brains; MUSE: an ensemble multi-atlas parcellation; Schaefer: a local-global parcellation of the human cerebral cortex from intrinsic functional connectivity MRI; Talairach: automated Talairach atlas labels for functional brain mapping; Yeo: the organization of the human cerebral cortex estimated by intrinsic functional connectivity.
