Journal ArticleDOI
The role of prefrontal cortex in working memory: examining the contents of consciousness.
TL;DR: Evidence from brain-imaging studies that prefrontal cortex shows sustained activity during the delay period of visual working memory tasks, indicating that this cortex maintains on-line representations of stimuli after they are removed from view is presented.
Journal ArticleDOI
Evidence for a direct association between cortical atrophy and cognitive impairment in relapsing-remitting MS

TL;DR: Findings indicate that MS-related deficits in cognition are closely associated with cortical atrophy, compatible with the progression of atrophy found in more advanced MS-patients.
Journal ArticleDOI
Attention and cognitive control as emergent properties of information representation in working memory.
TL;DR: Evidence is reviewed suggesting that a unifying principle regarding the role of various portions of the prefrontal cortex in a wide range of cognitive tasks is the active maintenance in working memory of different types of currently relevant information.
Journal ArticleDOI
Functional topography of a distributed neural system for spatial and nonspatial information maintenance in working memory
TL;DR: The results suggest that there is a consistent functional topography that results in superior prefrontal cortex producing the greatest response during spatial WM tasks, and middle and inferior prefrontal cortices producing their greatest responses during objectWM tasks, independent of the object type.
Journal ArticleDOI
Association of Cortical Lesion Burden on 7-T Magnetic Resonance Imaging With Cognition and Disability in Multiple Sclerosis

TL;DR: To evaluate the clinical relevance of measures of CL burden derived from high-field magnetic resonance imaging (MRI) in multiple sclerosis, an observational clinical imaging study conducted at an academic MS center found that increasing log[CL volume] conferred a 3-fold increase in the odds of cognitive impairment.
