Abnormalities of intrinsic functional connectivity in autism spectrum disorders,
Autism spectrum disorders (ASD) impact social functioning and communication, and individuals with these disorders often have restrictive and repetitive behaviors. Accumulating data indicate that ASD is associated with alterations of neural circuitry. Functional MRI (FMRI) studies have focused on connectivity in the context of psychological tasks. However, even in the absence of a task, the brai...
متن کاملResting state arousal and functional connectivity in autism spectrum disorder.
A recent study (Eilam-Stock T, Xu P, Cao M, Gu X, Van Dam NT, Anagnostou E, Kolevzon A, Soorya L, Park Y, Siller M, He Y, Hof PR, Fan J. Brain 137: 153-171, 2014) demonstrated that resting state electrodermal activity is correlated with different patterns of brain activity in subjects with autism spectrum disorder (ASD) than in typical controls. These results are considered in light of theories...
متن کاملFunctional connectivity in a baseline resting-state network in autism.
Brain activity in people with high-functioning autism has been shown to be atypical in a number of ways, including reduced synchronization across areas of activation measured by functional magnetic resonance imaging. This activation atypicality has been observed mostly during the performance of cognitive tasks. This study compares the resting-state network of 57 participants with autism and 57 ...
متن کاملResting-State Functional Connectivity in Autism Spectrum Disorders: A Review
Ongoing debate exists within the resting-state functional MRI (fMRI) literature over how intrinsic connectivity is altered in the autistic brain, with reports of general over-connectivity, under-connectivity, and/or a combination of both. Classifying autism using brain connectivity is complicated by the heterogeneous nature of the condition, allowing for the possibility of widely variable conne...
متن کاملThe Influence of Brain State on Functional Connectivity in Autism.
that the disorder involves atypical development of brain connectivity, several open questions remain with regard to the precise nature of these atypicalities. A limitation of the current neuroimaging literature is a focus on adulthood autism, with recent work beginning to examine late childhood and adolescence (Uddin et al., 2013). In this issue of EBioMedicine, Buckley and colleagues contribut...
