Fragile X syndrome (FraX) is the most common form of inherited mental deficit and is caused by mutations of the Fragile X Mental Retardation 1 ( FMR1 ) gene on the X chromosome. While males and females with the full FMR1 mutation are affected differently because the disorder is X‐linked, both suffer from varying degrees of cognitive impairment, att...

Functional imaging in humans and anatomical data in monkeys have implicated the insula as a multimodal sensory integrative brain region. The topography of insular connections is organized by its cytoarchitectonic regions. Previous attempts to measure the insula have utilized either indirect or automated methods. This study was designed to develop a...

a b s t r a c t Psychotic major depression (PMD) is associated with deficits in verbal memory as well as other cognitive impairments. This study investigated brain function in individuals with PMD during a verbal declarative memory task. Participants included 16 subjects with PMD, 15 subjects with non-psychotic major depression (NPMD) and 16 health...

Recent data suggests that psychotic major depression (PMD) may be a discrete disorder distinguishable from nonpsychotic major depression (NPMD), and that patients with PMD may be more similar to individuals with schizophrenia than individuals with NPMD. The insula is a brain region in which morphometric changes have been associated with psychotic s...

Autism Spectrum Disorder (ASD) is hallmarked by social-emotional reciprocity deficits. Social-emotional responding requires the clear recognition of social cues as well as the internal monitoring of emotional salience. Insular cortex is central to the salience network, and plays a key role in approach-avoidance emotional valuation. Consistent right...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social and communicative deficits. Previous research has focused on unearthing physical brain changes that occur in the disorder using various surface based metrics. However, there exists conflict between the results and the implications of them. The current study atte...

Insular Cortex, a multimodal region with connectivity throughout the brain, has a role in numerous clinical disorders. Manual morphometry is the ideal means to measure volume of insular cortex, in order to capture subtle inter-subject variability, but is very time consuming. Automated image processing is far more efficient, but is susceptible to lo...

Insular Cortex, while being one of the most highly integrative regions of the brain, continues to be one the least understood. Previous studies have found cytoarchitectural subregions within insular cortex, each with unique patterns of connectivity with other brain regions. Taken together, along with more recent functional analyses, evidence sugges...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by social and communication deficits and repetitive behaviors. Considerable work has focused on characterizing the neurobiological sequelae of this disorder, but no reliable pathognomonic biological marker of this disease has yet emerged. One potential reason is that most...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by verbal and nonverbal communication deficits and repetitive behaviors. Numerous studies have used voxel-based morphometry (VBM), a coordinate-based methodology, to assess localized neuroanatomical differences in ASD. VBM studies have noted differences in brain regions i...

Autism spectrum disorder (ASD) is a complex neurobiological developmental disorder, characterized by impaired social communication and social reciprocity, repetitive stereotypic behaviors, and high comorbidity of anxiety disorders. Prevailing theories of ASD suggest malfunction of individual brain regions, including amygdala, superior temporal sulc...

Alzheimer’s disease (AD) is an irreversible, progressive form of dementia that affects memory, thinking, and behavior. AD is the leading cause of dementia in aging adults, and it is the fifth leading cause of death in Americans aged 65 and older (Hua, Parikshak, Lee, Chiang, Toga, et al., 2008). Structural magnetic resonance imaging (MRI) scans in...

The counterclockwise brain torque, defined as a larger right prefrontal and left parietal-occipital lobe, is a consistent brain asymmetry. Reduced or reversed lobar asymmetries are markers of atypical cerebral laterality and have been found in adults who stutter. It was hypothesized that atypical brain torque would be more common in children who st...
