Reorganization of brain networks in aging: a review of functional connectivity studies

Description: Healthy aging (HA) is associated with certain declines in cognitive functions, even in individuals that are free of any process of degenerative illness. Functional magnetic resonance imaging (fMRI) has been widely used in order to link this age-related cognitive decline with patterns of altered brai...

Perfil de memoria en el trastorno por déficit de atención con hiperactividad.

Description: The objective of this study is to contribute to the establishment of a memory profile in subjects with attention deficit disorder with hyperactivity (ADHD). We examined fifty-one adolescents: 16 ADHD and 35 controls, aged between 14 and 16. Neuropsychological exploration included tests of short-term...

Alteraciones neuropsicológicas en el alcoholismo crónico

Description: El déficit neuropsicológico asociado al alcholismo abarca diversas funciones: memoria, razonamiento abstracto, solución de problemas y ha- bilidades perceptivo-motoras. Estructuralmente, los cambios cerebrales ob- servados con m i s frecuencia en la Tomografia Computarizada (TC) son la atrofia cereb...

Functional networks and structural connectivity of visuospatial and visuoperceptual working memory

Description: Neural correlates of working memory (WM) in healthy subjects have been extensively investigated using functional MRI (fMRI). However it still remains unclear how cortical areas forming part of functional WM networks are also connected by white matter fiber bundles, and whether DTI measures, used as ...

Visuospatial and visuoperceptual impairment in relation to global atrophy in Parkinson's diseas

Description: Parkinson's disease (PD) patients differed from controls of similar age in visuospatial and visuoperceptual functions at diagnosis moment, and these deficits have been shown to be neuropsychological markers of evolution to dementia. The aim of this study was to relate these dysfunctions with measure...

Dynamic funcitonal reorganizations and relationships with working memory performance in healthy aging

Description: In recent years, several theories have been proposed in attempts to identify the neural mechanisms underlying successful cognitive aging. Old subjects show increased neural activity during the performance of tasks, mainly in prefrontal areas, which is interpreted as a compensatory mechanism linked t...

Rich club organization and cognitive performance in healthy older participants

Description: The human brain is a complex network that has been noted to contain a group of densely interconnected hub regions. With a putative 'rich club' of hubs hypothesized to play a central role in global integrative brain functioning, we assessed whether hub and rich club organizations are associated with ...

Combination of diffusion tensor and functional magnetic resonance imaging during recovery from the vegetative state

Description: Background: The rate of recovery from the vegetative state (VS) is low. Currently, little is known of the mechanisms and cerebral changes that accompany those relatively rare cases of good recovery. Here, we combined functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) to ...

Discriminating cognitive status in Parkinson's disease through functional connectomics and machine learning

Description: There is growing interest in the potential of neuroimaging to help develop non-invasive biomarkers in neurodegenerative diseases. In this study, connection-wise patterns of functional connectivity were used to distinguish Parkinson's disease patients according to cognitive status using machine learn...

Cortical thickness and behavior abnormalities in children born preterm

Description: Abstract Aim To identify long-term effects of preterm birth and of periventricular leukomalacia (PVL) on cortical thickness (CTh). To study the relationship between CTh and cognitive-behavioral abnormalities. Methods We performed brain magnetic resonance imaging on 22 preterm children with PVL, 14 p...
