Structural brain networks were constructed based on diffusion tensor imaging (DTI) data of 59 young healthy male adults. The networks had 68 nodes, derived from FreeSurfer parcellation of the cortical surface. By means of streamline tractography, the edge weight was defined as the number of streamlines between two nodes normalized by their mean volume.(More)
OBJECTIVE To understand better the relation between media violence exposure, brain functioning, and trait aggression, this study investigated the association between media violence exposure and brain activation as measured by functional magnetic resonance imaging (fMRI) in groups of normal adolescents and adolescents with disruptive behavior disorder (DBD)(More)
A large body of clinical research over the last decade demonstrates that cochlear implants work and provide significant speech and language benefits to profoundly deaf adults and prelingually deaf children. The most challenging research problem today is that cochlear implants do not work equally well for everyone who has a profound hearing loss and cochlear(More)
Sound is inherently a temporal and sequential signal. Experience with sound therefore may help bootstrap - i.e., provide a kind of "scaffolding" for - the development of general cognitive abilities related to representing temporal or sequential patterns. Accordingly, the absence of sound early in development may result in disturbances to these sequencing(More)
OBJECTIVES Conventional assessments of outcomes in deaf children with cochlear implants (CIs) have focused primarily on endpoint or product measures of speech and language. Little attention has been devoted to understanding the basic underlying core neurocognitive factors involved in the development and processing of speech and language. In this study, we(More)
The relationship between media violence exposure and executive functioning was investigated in samples of adolescents with no psychiatric diagnosis or with a history of aggressive-disruptive behavior. Age-, gender-, and IQ-matched samples of adolescents who had no Diagnostic and Statistical Manual of Mental Disorders-fourth edition (DSM-IV; American(More)
PURPOSE To evaluate the family environments of children with cochlear implants and to examine relationships between family environment and postimplant language development and executive function. METHOD Forty-five families of children with cochlear implants completed a self-report family environment questionnaire (Family Environment Scale--Fourth Edition;(More)
Progress in biomedical technology (cochlear, vestibular, and retinal implants) has led to remarkable success in neurosensory restoration, particularly in the auditory system. However, outcomes vary considerably, even after accounting for comorbidity-for example, after cochlear implantation, some deaf children develop spoken language skills approaching those(More)
IMPORTANCE Children who receive a cochlear implant (CI) for early severe to profound sensorineural hearing loss may achieve age-appropriate spoken language skills not possible before implantation. Despite these advances, reduced access to auditory experience may have downstream effects on fundamental neurocognitive processes for some children with CIs. (More)
BACKGROUND To evaluate the effect of atomoxetine (ATX) on attention-deficit/hyperactivity disorder (ADHD) and comorbid social anxiety disorder in adults. METHODS Randomized, double-blind, placebo-controlled, conducted in adults with ADHD and social anxiety disorder. Patients received 40-100 mg ATX (n=224) or placebo (n=218) for 14 weeks following a 2-week(More)
