Altered task‐related modulation of long‐range connectivity in children with autism

Abstract: Decreased connectivity between brain regions is thought to cause the symptoms of autism. Because most of our knowledge comes from data in which children are at rest, we do not know how connectivity changes directly lead to autistic behaviors, such as impaired gestures. When typically developing children produced complex movements, connectivity decreased between brain regions. In children with autism, connectivity increased. It may be that behavior-related changes in brain connectivity are more important than a… Show more

“…We selected regions of interest (ROI) targeting the left and right primary cortex based on experience with prior motor‐control datasets (Ewen et al, ; Ewen, Lakshmanan, et al, ; Ewen, Pillai, et al, ; Pillai et al, ; Figure ). For ease of language, we will refer to brain activity relative to the side of the intentional movement.…”

“…Tsiaras et al ( 2011 ) used a well-established graph measures which served as features in classifying controls and young adults with ASD. Pillai et al ( 2018 ) used the electroencephalography (EEG) and a movement-based paradigm to examine the FC changes in ASD children while performing specific tasks. Anderson et al ( 2011 ) characterized a whole-brain functional connectivity abnormalities in a data-driven fashion to identify the regions showing greatest differences between individual subjects with autism and developing controls.…”

“…Motor impairments have been known in ASD since Kanner's original description [Kanner, ] and are highly prevalent in the disorder [Vanvuchelen, Roeyers, & De Weerdt, ; Weimer, Schatz, Lincoln, Ballantyne, & Trauner, ]. They may be either reflective of the similar pathophysiological processes that cause the cardinal symptoms of ASD or even causally involved in the pathophysiology of the social‐communicative phenotype [Denckla, ; Ewen et al, ; Gowen & Hamilton, ; Lloyd, MacDonald, & Lord, ; Mostofsky et al, ; Mostofsky & Ewen, ; Mous et al, ; Pillai et al, ]. Severe congenital motor deficits—cerebral palsy—are independently associated with epilepsy [Gururaj, Sztriha, Bener, Dawodu, & Eapen, ; Wallace, ], but such severe deficits make up only a small fraction of the high proportion of children with ASD who often have more subtle motor deficits.…”
