Journal ArticleDOI
Physiotherapy Coupled With Dextroamphetamine for Rehabilitation After Hemiparetic Stroke: A Randomized, Double-Blind, Placebo-Controlled Trial
David J. Gladstone,Cynthia J. Danells,Armi Armesto,William E. McIlroy,W. Richard Staines,Simon J. Graham,Nathan Herrmann,John P. Szalai,Sandra E. Black +8 more
TL;DR: In stroke patients with a severe motor deficit, 10 mg AMPH coupled with physiotherapy twice per week for 5 weeks in the early poststroke period provided no additional benefit in motor or functional recovery compared with physiotherapist alone.
Journal ArticleDOI
Brain activity during driving with distraction: an immersive fMRI study
TL;DR: The findings suggest that the distracted brain sacrificed areas in the posterior brain important for visual attention and alertness to recruit enough brain resources to perform a secondary, cognitive task.
Journal ArticleDOI
In vivo characterization of traumatic brain injury neuropathology with structural and functional neuroimaging.
Brian Levine,Esther Fujiwara,Charlene O'Connor,Nadine M Richard,Natasa Kovacevic,Marina Mandic,Adriana Restagno,Craig Easdon,Ian H. Robertson,Simon J. Graham,Gordon Cheung,Fuqiang Gao,Michael L. Schwartz,Sandra E. Black +13 more
TL;DR: Results indicate that TBI causes a more widely dispersed activation in frontal and posterior cortices, and further progress in analysis of the consequences of TBI on neural structure and function will require control of variability in neuropathology and behavior.
Journal ArticleDOI
Optimizing preprocessing and analysis pipelines for single-subject fMRI. I. Standard temporal motion and physiological noise correction methods.
Nathan W. Churchill,Anita Oder,Hervé Abdi,Fred Tam,Wayne Lee,Christopher G. Thomas,Jon E. Ween,Simon J. Graham,Simon J. Graham,Stephen C. Strother +9 more
TL;DR: It is shown that the quality of brain activation maps may be significantly limited by sub‐optimal choices of data preprocessing steps (or “pipeline”) in a clinical task‐design, an fMRI adaptation of the widely used Trail‐Making Test, and that individually‐optimized pipelines may significantly improve the reproducibility of fMRI results over fixed pipelines.
Journal ArticleDOI
Investigation of fMRI neurofeedback of differential primary motor cortex activity using kinesthetic motor imagery
TL;DR: Results indicate that fMRI NF of kMI is capable of modulating brain activity in primary motor regions in a subset of the population, and such methods may be useful in the development of NF training methods for enhancing motor rehabilitation following stroke.
