New paper on Journal of Neuroscience
A new paper by Esin Karahan and our collaborators is published on the Journal of Neuroscience. We showed that higher DWI-based neurite density in the corticospinal tract is negatively associated with action speed in a simple reaction time task. Our results confirmed the common assumption that the non-decision time is rooted in the primary motor pathway of the brain. We put forward a simple analysis pipeline to search for structural-functional associations along the principal direction of fiber bundles, which would be useful in further studies on anatomically specific brain-behaviour associations.
The paper is now available online.
