Scoping literature review: Comparing MRI tractography methods for optic radiation analysis

The Anatomical Record, EarlyView.
Abstract Accurate tractography mapping of the optic radiations is essential to avoiding post‐operative visual field deficits in patients undergoing temporal lobe surgery. This literature review highlights the current landscape of MRI tractography methods that are used to delineate the optic radiations (ORs), with a particular focus on the anterior ...

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

The translational asymmetry of corpus callosotomy: Two literatures that answered different questions

Epilepsia Open, EarlyView.
Abstract Corpus callosotomy is an established palliative operation for drug‐resistant epilepsy dominated by drop attacks, and it is performed in three extents: anterior, usually of the anterior two‐thirds; total, in one or two stages; and selective posterior, which preserves the genu and rostral body.
