Distinct genetic influences on cortical surface area and cortical thickness.
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 aExpand

Influence of patients' requests for direct-to-consumer advertised antidepressants: a randomized controlled trial.
CONTEXT Direct-to-consumer (DTC) advertising of prescription drugs in the United States is both ubiquitous and controversial. Critics charge that it leads to overprescribing, while proponents counterExpand

Genome-wide analyses for personality traits identify six genomic loci and show correlations with psychiatric disorders
Personality is influenced by genetic and environmental factors and associated with mental health. However, the underlying genetic determinants are largely unknown. We identified six genetic loci,Expand

Genetic and environmental influences on the size of specific brain regions in midlife: The VETSA MRI study
The impact of genetic and environmental factors on human brain structure is of great importance for understanding normative cognitive and brain aging as well as neuropsychiatric disorders. However,Expand

Pathways to Dementia Diagnosis: Evidence for Cross-Ethnic Differences
SummaryThe diagnosis of dementia often occurs well after the onset of the disease. Studies of help-seeking behavior may help illuminate why delays occur. Specific Aims(1) To describe pathways toExpand

A 35-year longitudinal assessment of cognition and midlife depression symptoms: the Vietnam Era Twin Study of Aging.
OBJECTIVE To determine whether early adult cognitive ability is a risk factor for depressive symptoms in midlife and how genetic and environmental influences explain the association and to examineExpand

Hierarchical Genetic Organization of Human Cortical Surface Area
Building the Brain Brain connectivity is often described as a network of discrete independent cables analogous to a switchboard, but how is the physical structure of the brain constructed (see theExpand

Salivary cortisol and prefrontal cortical thickness in middle-aged men: A twin study
Although glucocorticoid receptors are highly expressed in the prefrontal cortex, the hippocampus remains the predominant focus in the literature examining relationships between cortisol and brain. WeExpand

A comparison of heritability maps of cortical surface area and thickness and the influence of adjustment for whole brain measures: a magnetic resonance imaging twin study.
Understanding the genetic and environmental contributions to measures of brain structure such as surface area and cortical thickness is important for a better understanding of the nature ofExpand
