The results contradict the so-called connectivity theory of autism, which holds that the brains of people with the disorder have weak long-range functionalThe default mode network is active when the brain is not performing a cognitive task. Comparing 28 children with autism and 28 controls, ages 8 to Dysmaturation of the default mode network in autism. (English). Abstract/OtherAbstract: The default mode network (DMN) is a collection ofWe investigated the DMN in 13 high-functioning adults with autism spectrum disorders (ASD) and 14 typically developing control participants during three fMRI studies (two language tasks and a Theory-of-Mind (ToM) task). These studies suggest the pathophysiology of autism includes widespread deficits across structural and functional networks, rather thanRegions of the default mode network are involved in tasks that require language (for example, internal narrative and autobiographical memory) and theory of mind This theory predicts that any feature of autism in males should 1) be present in autistic females, 2)Here we tested these three predictions for default mode network (DMN) hypoconnectivity during resting state, one of the most robustly found neurobiological differences in autism.

Baron-Cohen S, Leslie AM, Frith U (1985): Does the autistic child have a theory of mind ? In neuroscience, the default mode network (DMN), also default network, or default state network, is a large scale brain network of interacting brain regions known to have activity highly correlated with each other and distinct from other networks in the brain. Abstract. Autism spectrum disorders (ASDs) are characterized by deficits in social and communication processes. Recent data suggest that altereddefault mode network (DMN), a network active during passive resting states and cognitive processes related to social deficits seen in ASD, e.
