Corticocortical and Thalamocortical Resting State Sensory Area Correlations Are Atypical in Autism (original) (raw)

Abstract

Background: Autism is characterized by a broad range of atypicalities in perceptual processing, notably including advantages in visual search, figure/ground discrimination, block design and pitch discrimination. It has been suggested that these differences may arise from variations in the local influences governing the interactions among collections of neighboring, functionally related sensory regions responsible for the early stages of perception. The examination of resting state correlations allows exploration of inter-regional interactions occurring in a part of the frequency spectrum lower than that usually thought to support the flow of information associated with task-related activity. As such, the strength and spatial pattern of these correlations may provide complementary information concerning the anatomical and functional infrastructure supporting perceptual system operation in autistics. Objectives: To compare the patterns of functional correlations in perceptual brain re...
