Journal ArticleDOI
Cortical activation and synchronization during sentence comprehension in high-functioning autism: evidence of underconnectivity
TL;DR: The findings suggest that the neural basis of disordered language in autism entails a lower degree of information integration and synchronization across the large-scale cortical network for language processing.
Journal ArticleDOI
Brain Activation Modulated by Sentence Comprehension
TL;DR: The comprehension of visually presented sentences produces brain activation that increases with the linguistic complexity of the sentence, and the amount of neural activity that a given cognitive process engenders is dependent on the computational demand that the task imposes.
Journal ArticleDOI
Functional and anatomical cortical underconnectivity in autism: Evidence from an fMRI study of an executive function task and corpus callosum morphometry

TL;DR: The brain activation of a group of high-functioning autistic participants was measured using functional magnetic resonance imaging during the performance of a Tower of London task, in comparison with a control group matched with respect to intelligent quotient, age, and gender to suggest underconnectivity in the group with autism.
Journal ArticleDOI
Functional connectivity in a baseline resting-state network in autism.
TL;DR: The results indicate that both groups have a resting-state network that is very similar both in volume and in organization, but in autism this network is much more loosely connected.
Journal ArticleDOI
Functional connectivity in an fMRI working memory task in high-functioning autism
Hideya Koshino,Patricia A. Carpenter,Nancy J. Minshew,Vladimir L. Cherkassky,Timothy A. Keller,Marcel Adam Just +5 more
TL;DR: An fMRI study was used to measure the brain activation of a group of adults with high-functioning autism compared to a Full Scale and Verbal IQ and age-matched control group during an n-back working memory task with letters, suggesting that the normal controls might use verbal codes to perform the task, while the adults with autism might use visual codes.
