BACKGROUND Recognition of individual faces is an integral part of both interpersonal interactions and successful functioning within a social group. Therefore, it is of considerable interest that individuals with autism and related conditions have selective deficits in face recognition (sparing nonface object recognition). METHOD We used functional magnetic resonance imaging (fMRI) to study fa...
Increasing neuroimaging evidence suggests that autism patients exhibit abnormal brain structure and function. We used the Autism Brain Imaging Data Exchange (ABIDE) sample to analyze locally focal (~8 mm) functional connectivity of 223 autism patients and 285 normal controls from 15 international sites using a recently developed surface-based approach. We observed enhanced local connectivity in...
Deficits in facial mimicry have been widely reported in autism. Some studies have suggested that these deficits are restricted to spontaneous mimicry and do not extend to volitional mimicry. We bridge these apparently inconsistent observations by testing the impact of reward value on neural indices of mimicry and how autistic traits modulate this impact. Neutral faces were conditioned with high...
Objective: To investigate cerebellar function in autism by measuring visually guided saccades. Methods: A visually guided saccade task was performed by 46 high-functioning individuals with autism with and without delayed language acquisition, and 104 age and IQ matched healthy individuals. Results: Individuals with autism had increased variability in saccade accuracy, and only those without del...
Mutations in a synaptic organizing pathway contribute to autism. Autism-associated mutations in MDGA2 (MAM domain containing glycosylphosphatidylinositol anchor 2) are thought to reduce excitatory/inhibitory transmission. However, we show that mutation of Mdga2 elevates excitatory transmission, and that MDGA2 blocks neuroligin-1 interaction with neurexins and suppresses excitatory synapse devel...
Objectives: Autism is one subsets of pervasive developmental disorders that are characterized by abnormal behaviors and verbal communication. In recent years, the reason for this communication disorder has been developed for determining executive function. The current study investigated the feasibility of audiovisual stimulation intervention focused on enhancing executive function in children w...
When considering the cognitive abilities of people with autism, the majority of studies have explored domains in which there are deficits. However, on tests of local processing and visual search, exemplified by the Embedded Figures Task (EFT), people with autism have been reported to demonstrate superiority over normal controls. This study employed functional MRI of subjects during the performa...
In this review article, we summarize recent progress toward understanding the neural structures and circuitry underlying dysfunctional social cognition in autism. We review selected studies from the growing literature that has used the functional neuroimaging techniques of cognitive neuroscience to map out the neuroanatomical substrates of social cognition in autism. We also draw upon functiona...
The most replicated finding in autism neuroanatomy-a tendency to unusually large brains-has seemed paradoxical in relation to the specificity of the abnormalities in three behavioral domains that define autism. We now know a range of things about this phenomenon, including that brains in autism have a growth spurt shortly after birth and then slow in growth a few short years afterward, that onl...
Background: This is a case series of 76 knees of 62 patients who underwent upper tibial valgus osteotomy for treatment of medial compartment osteoarthritis during a 20-year period and who were followed for a mean of 7.6 years. Methods: The patients were evaluated by validated outcome assessment systems of general health status short form (SF-36), the Western Ontario McMaster osteoarthritis inde...
