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)
—Sound is inherently a temporal and sequential signal. Experience with sound therefore may help boot-strap—that is, 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)
PURPOSE This study investigated the feasibility and efficacy of a working memory training program for improving memory and language skills in a sample of 9 children who are deaf (age 7-15 years) with cochlear implants (CIs). METHOD All children completed the Cogmed Working Memory Training program on a home computer over a 5-week period. Feasibility and(More)
Diffusion tensor imaging (DTI) has been used for mapping the structural network of the human brain. The network can be constructed by choosing various brain regions as nodes and fiber tracts connecting those regions as links. The structural network generated from DTI data can be affected by noise in the scans and the choice of tractography algorithm. This(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)
of Medicine has been concerned with understanding the large individual differences in speech and language outcomes in deaf children who have received cochlear implants (CIs). We are interested in explaining and predicting the enormous variability observed in a wide range of conventional measures of speech and language following cochlear implantation. The(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)
We assessed profoundly deaf children with cochlear implants (CIs) (N = 24) and age-matched normal-hearing children (N = 31) on several nonverbal cognition measures: motor sequencing, tactile discrimination, response inhibition, visual-motor integration, and visual-spatial processing. The results revealed that the children with CIs showed disturbances solely(More)
The dual-component model contends that working memory (WM) capacity consists of two components. The first is a flexible attention component that involves the active maintenance of a limited amount of information in primary memory (PM), and the second is a controlled retrieval component that involves a cue-dependent search of secondary memory (SM) for(More)
