MRI-HARDI Rotating 3D Brains

New brain analysis video illustrating differences in the integrity of key visual pathways.

Rotating 3D view of standard structural magnetic resonance imaging (MRI; grey matter rendering), then whole brain High Angular Resolution Diffusion Imaging (HARDI) showing white matter connections, and then virtual dissection revealing visual pathways originating from the occipital pole (dorsal and ventral visual processing streams). Images are taken from an age matched control subject with neurotypical visual development (left) and an individual with cerebral/cortical visual impairment (CVI) associated with periventricular leukomalacia (PVL) (right). Note the lack of full development of the dorsal and ventral visual pathways in CVI compared to the control individual. Current work is looking at how these connections can be enhanced with rehabilitation.
