Connectograms based on diffusion MRI data employ graphs to demonstrate white matter connections and cortical characteristics. Connectograms can inform treatment of patients with neuroanatomical abnormalities. They can also be used for average cortical metrics and tractography data, across populations of any size.
The outermost cortical surface ring:
Left and right depicts respective hemispheres
Hemispheres comprise frontal lobe, insular cortex, limbic lobe, temporal lobe, parietal lobe, occipital lobe, subcortical structures, and cerebellum
Brain stem is represented between the two hemispheres at the bottom.
Inside the cortical ring represented such as:
Grey matter volume
Degree of connectivity
Inside the circles:
Lines connecting regions that are found to be structurally connected.
The opacity of the lines represent number of connections. Fiber color gives fractional anisotropy.
