Cognition arises as a result of coordinated processing among distributed brain regions and
disruptions to communication within these neural networks can result in cognitive …

In this article we review recent research on diffusion tensor imaging (DTI) of white matter
(WM) integrity and the implications for age-related differences in cognition. Neurobiological …

White matter disruption is an important determinant of cognitive impairment after brain injury,
but conventional neuroimaging underestimates its extent. In contrast, diffusion tensor …

Magnetic resonance imaging volumetry studies report inverted U-patterns with increasing
white-matter (WM) volume into middle age suggesting protracted WM maturation compared …

Background A growing body of evidence links socioeconomic status (SES) to children's
brain structure. Few studies, however, have specifically investigated relations of SES to …

There are many reports of relations between age and cognitive variables and of relations
between age and variables representing different aspects of brain structure and a few …

Motor chunking facilitates movement production by combining motor elements into
integrated units of behavior. Previous research suggests that chunking involves two …

BACKGROUND & AIMS: Patients with cirrhosis and minimal hepatic encephalopathy (MHE)
have driving difficulties but the effects of therapy on driving performance is unclear. We …

Part B of the Trail Making Test (TMT-B) is widely used as a quick and easy to administer
measure of executive dysfunction. The current study investigated the relationships between …

The ability to perform complex as well as simple cognitive tasks engages a network of brain
regions that is mediated by the white matter fiber bundles connecting them. Different …
