Connectome construction of a patient with a tumor in the speech-eloquent area of the brain.
The connection strengths of the white matter are shown as edges with a heat map (dark = weak connection, light = strong connection). The cortical areas of the brain and their size are illustrated as nodes in the form of spheres. Additionally, three orange TMS points are shown (TMS = Transcranial Magnetic Stimulation). In this case, the patient’s speech network could be non-invasively disturbed in these areas and mapped accordingly.

The visualization of the white matter is based on tractography. The different directions of the white matter can be measured and displayed by means of diffusion-weighted magnetic resonance imaging. Copyright: Lucius Fekonja & Image Guidance Lab, Charité – Universitätsmedizin Berlin
