Dynamics of White Matter Plasticity Underlying Working Memory Training: Multimodal Evidence from Diffusion MRI and Relaxometry

Claudia Metzler-Baddeley, Sonya Foley, Silvia de Santis, Cyril Charron, Adam Hampshire, Karen Caeyenberghs, Derek K. Jones
2017 Journal of Cognitive Neuroscience  
■ Adaptive working memory (WM) training may lead to cognitive benefits that are associated with white matter plasticity in parietofrontal networks, but the underlying mechanisms remain poorly understood  ...  fraction from the composite hindered and restricted model of diffusion as an estimate of axon morphology, and fractional anisotropy and radial diffusivity from diffusion ten-sor imaging.  ...  coregistration, Flavio dell'Acqua and Michel Thibaut de Schotten, London, for their advice regarding SLF subfascicle reconstructions, and Naomi Warne, Cardiff, for help with some of the tract reconstruction  ...

Dynamics of the Human Structural Connectome Underlying Working Memory Training

K. Caeyenberghs, C. Metzler-Baddeley, S. Foley, D. K. Jones
2016 Journal of Neuroscience  
Adaptive working memory training led to improvement on (non)trained working memory tasks and generalization to tasks of reasoning and inhibition.  ...  Furthermore, the impact of different diffusion MR metrics and more specific markers of white matter on the graph theoretical findings was evaluated.  ...  There is evidence from diffusion tensor MRI studies that cognitive training can modify white matter fractional anisotropy (FA), a quantitative index of tissue microstructural organization (e.g., Scholz  ...

Plasticity in gray and white: neuroimaging changes in brain structure during learning

Robert J Zatorre, R Douglas Fields, Heidi Johansen-Berg
2012 Nature Neuroscience  
Human brain imaging has identified structural changes in gray and white matter that occur with learning.  ...  Here we review human neuroimaging findings of structural plasticity and then discuss cellular and molecular level changes that could underlie observed imaging effects.  ...  Reprints and permissions information is available online at http://www.nature.com/ reprints/index.html.  ...

Brain microstructure by multi-modal MRI: Is the whole greater than the sum of its parts?

Mara Cercignani, Samira Bouyagoub
2017 NeuroImage  
This forms the basis of multi-modal MRI, a broad concept that refers to many different ways of effectively combining information from more than one MRI contrast.  ...  A strategy to overcome this limitation lies in the combination of more than one technique, to exploit the relative contributions of differing physiological and pathological substrates to selected MRI contrasts  ...  This is because most of the work done to date concerns the white matter, and models of the MRI signal in white matter are usually less ambiguous than those of the grey matter.  ...

Insights and Perspectives on Sensory-Motor Integration and Rehabilitation

Rochelle Ackerley, Michael Borich, Silvio Ionta, Calogero Maria Oddo
2016 Multisensory Research  
Specifically, where incoming sensory signals from the periphery are processed and interpreted to initiate behaviors, and how ongoing behaviors produce sensory consequences encoded and used to fine-tune  ...  The work reviewed here shows that it is imperative to understand the fundamental mechanisms of the somatosensory-motor system to restore accurate motor abilities and appropriate somatosensory feedback.  ...  Acknowledgements This work was supported by the Swiss National Science Foundation through the Ambizione funding program to Silvio Ionta (grant PZ00P1_148186), and by the Italian Ministry for Education,  ...
