Cora E. Mukerji; John S. Wilson III; Carol L. Wilkinson; Manon A. Krol; Charles A. Nelson; Helen Tager-Flusberg – Journal of Autism and Developmental Disorders, 2025
Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Choi, Ja Young; Choi, Yoon Seong; Park, Eun Sook – Journal of Speech, Language, and Hearing Research, 2017
Purpose: The purpose of this study was to investigate characteristics of language development in relation to brain magnetic resonance imaging (MRI) characteristics and the other contributing factors to language development in children with cerebral palsy (CP). Method: The study included 172 children with CP who underwent brain MRI and language…

Warren, Jane E.; Crinion, Jennifer T.; Ralph, Matthew A. Lambon; Wise, Richard J. S. – Brain, 2009
Focal brain lesions are assumed to produce language deficits by two basic mechanisms: local cortical dysfunction at the lesion site, and remote cortical dysfunction due to disruption of the transfer and integration of information between connected brain regions. However, functional imaging studies investigating language outcome after aphasic…

Reynolds Losin, Elizabeth A.; Rivera, Susan M.; O'Hare, Elizabeth D.; Sowell, Elizabeth R.; Pinter, Joseph D. – American Journal on Intellectual and Developmental Disabilities, 2009
Down syndrome is characterized by disproportionately severe impairments of speech and language, yet little is known about the neural underpinnings of these deficits. We compared fMRI activation patterns during passive story listening in 9 young adults with Down syndrome and 9 approximately age-matched, typically developing controls. The typically…

Russo, Nicole; Nicol, Trent; Trommer, Barbara; Zecker, Steve; Kraus, Nina – Developmental Science, 2009
Language impairment is a hallmark of autism spectrum disorders (ASD). The origin of the deficit is poorly understood although deficiencies in auditory processing have been detected in both perception and cortical encoding of speech sounds. Little is known about the processing and transcription of speech sounds at earlier (brainstem) levels or…

Rondal, Jean A.; Comblain, Annick – Down Syndrome Research and Practice, 2002
Several cross-sectional studies and one longitudinal study were conducted on the language abilities of various cohorts of persons with Down syndrome (ages 14-50). A gradual decrease in global cerebral metabolic rate (CMR) for both hemispheres and for each participant was documented, however, no language deterioration could be associated with CMR…
