Interdatabase Variability in Cortical Thickness Measurements

Cerebral Cortex, 2018
Abstract The phenomenon of cortical thinning with age has been well established; however, the measured rate of change varies between studies. The source of this variation could be image acquisition techniques including hardware and vendor specific differences.

The contribution of genes to cortical thickness and volume [PDF]

NeuroReport, 2011
We analyzed brain MRI data from 372 young adult twins to identify cortical regions in which gray matter thickness and volume are influenced by genetics. This was achieved using an A/C/E structural equation model that divides the variance of these traits, at each point on the cortex, into additive genetic (A), shared (C), and unique environmental (E ...

Reduced Cortical Thickness in Mental Retardation

PLoS ONE, 2011
Mental retardation is a developmental disorder associated with impaired cognitive functioning and deficits in adaptive behaviors. Many studies have addressed white matter abnormalities in patients with mental retardation, while the changes of the cerebral cortex have been studied to a lesser extent.

Age-Related Differences in Cortical Thickness Vary by Socioeconomic Status. [PDF]

PLoS ONE, 2016
Recent findings indicate robust associations between socioeconomic status (SES) and brain structure in children, raising questions about the ways in which SES may modify structural brain development.

Cerebral Cortical Thickness in Chronic Pain Due to Knee Osteoarthritis: The Effect of Pain Duration and Pain Sensitization. [PDF]

PLoS ONE, 2016
OBJECTIVE:This study investigates associations between cortical thickness and pain duration, and central sensitization as markers of pain progression in painful knee osteoarthritis. METHODS:Whole brain cortical thickness and pressure pain thresholds were

Distinct Genetic Influences on Cortical Surface Area and Cortical Thickness [PDF]

Cerebral Cortex, 2009
Neuroimaging studies examining the effects of aging and neuropsychiatric disorders on the cerebral cortex have largely been based on measures of cortical volume. Given that cortical volume is a product of thickness and surface area, it is plausible that measures of volume capture at least 2 distinct sets of genetic influences. The present study aims to

Age differences in prefrontal surface area and thickness in middle aged to older adults

Frontiers in Aging Neuroscience, 2016
Age is associated with reductions in surface area and cortical thickness, particularly in prefrontal regions. There is also evidence of greater thickness in some regions at older ages.

Cortical thickness gradients in structural hierarchies

NeuroImage, 2015
MRI, enabling in vivo analysis of cortical morphology, offers a powerful tool in the assessment of brain development and pathology. One of the most ubiquitous measures used-the thickness of the cortex-shows abnormalities in a number of diseases and conditions, but the functional and biological correlates of such alterations are unclear.

Assessing Intracortical Myelin in the Living Human Brain Using Myelinated Cortical Thickness

Frontiers in Neuroscience, 2015
Alterations in the myelination of the cerebral cortex may underlie abnormal cortical function in a variety of brain diseases. Here, we describe a technique for investigating changes in intracortical myelin in clinical populations on the basis of ...

Overweight is not associated with cortical thickness alterations in children

Frontiers in Neuroscience, 2015
IntroductionSeveral studies report an association between body mass index (BMI) and cortical thickness in adults. Some studies demonstrate diffuse cortical thinning in obesity, while others report effects in areas that are associated with self-regulation,
