Activation patterns for repetitive index finger movement in three men with autism and three gender and age-matched control participants. All participants show activation clusters in the vicinity of the central sulcus contralateral to the side of movement (indicated by the green line). However, in individuals with autism activity tends to be widely scattered across fronto-parietal regions, whereas in control participants additional activity is largely limited to supplementary motor cortex in the medial frontal lobe and a few sites in ipsilateral motor and premotor cortex.
