Scientists should heed these differences when considering resting-state brain activity as a biomarker for autism, the researchers say.

Preliminary results suggested the treatment is no better than placebo at reducing the severity of core autism traits.
Brain responses to visual stimuli are smaller and weaker in children with Phelan-McDermid syndrome, an autism-linked genetic condition, than in non-autistic children.
Biological factors that reflect autism’s roots may differ from those that influence how severe the condition is. Failure to make a distinction has stymied the search for biomarkers.
The high levels of serotonin seen in the blood of some autistic people have confounded scientists for more than half a century. Despite so little progress, some researchers refuse to give up.
Q&A with Sébastien Jacquemont and Clara Moreau: Why brain imaging signatures for autism are so elusive
The field of neuroimaging will need to combine two strategies before it can find patterns of brain activity or structure unique to autism, the researchers say.
A delayed brain response to viewing faces may predict lags in social-skill development in autistic people.
A novel method to evaluate the strength of the evidence linking autism to specific genes could reveal which ones are most useful to screen for.
