Blue Brain Project | Mouse Neocortex Tractography

"View from below the neocortex rendered at 3% density. Showing long distance connections (white matter) between regions of the neocortex. Neurons are colored by morphological types and algorithmically synthesized." [EPFL | Switzerland | 2005—2020]

In neuroscience, tractography is a 3D modeling technique used to visually represent nerve tracts using data collected by diffusion MRI. It uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI. The results are presented in two- and three-dimensional images called tractograms. (Wikipedia)

•Diffusion MRI Fiber Tractography of the Brain•

This image shows complex patterns of connectivity of the human cortex measured in vivo with MRI via diffusion of water molecules in axons in the white matter.

The colors depict average directional anisotropy of white matter voxels (fractional anisotropy of a diffusion tensor model)

blue: more anisotropic

yellow: less anisotropic

Intraoperative MRI–based elastic fusion for anatomically accurate tractography of the corticospinal tract

Intraoperative MRI–based elastic fusion for anatomically accurate tractography of the corticospinal tract

Neurosurg Focus 50 (1):E9, 2021 Tractography is a useful technique that is standardly applied to visualize subcortical pathways. However, brain shift hampers tractography use during the course of surgery. While intraoperative MRI (ioMRI) has been shown to be beneficial for use in oncology, intraoperative tractography can rarely be performed due to scanner, protocol, or head clamp limitations.…

Tractography-Guided Deep Brain Stimulation of the Anteromedial Globus Pallidus Internus for Refractory Obsessive-Compulsive Disorder

Neurosurgery 86:E558–E563, 2020

Obsessive-compulsive disorder (OCD) is a disabling psychiatric disorder, mainly treated with psychotherapy and pharmacotherapy. Surgical intervention may be appropriate for patients with treatment-refractory OCD. Deep brain stimulation (DBS) is an alternative for previously common ablative surgical procedures. Tractography has been proposed as a method for…
