Disconnectome morphospace
Figure: Uniform Manifold Approximation and Projection (UMAP) [1] embedding of N=1333 stroke lesions [2].
Brain lobe annotations indicate the dominant location of each stroke lesion. R=right hemisphere; L=left hemisphere.
The disconnectome morphospace shown in the Figure above summarizes the UMAP (Uniform Manifold Approximation and Projection) importation of single patients in a common 2-dimensional space. The UMAP coordinates will be used to inform the neuropsychological scores prediction model [3].
