Successful face recognition is associated with increased prefrontal cortex activation in autism spectrum disorder . This study examines whether deficits in visual information processing in autism-spectrum disorder ( ASD ) can be offset by the recruitment of brain structures involved in selective attention . During functional MRI , 12 children with ASD and 19 control participants completed a selective attention one-back task in which images of faces and houses were superimposed . When attending to faces , the ASD group showed increased activation relative to control participants within multiple prefrontal cortex areas , including dorsolateral prefrontal cortex ( DLPFC ) . DLPFC activation in ASD was associated with increased response times for faces . These data suggest that prefrontal cortex activation may represent a compensatory mechanism for diminished visual information processing abilities in ASD .
