A well-studied mouse model of autism has a smaller-than-normal volume in several autism-associated brain regions.

Two new studies suggest that people with autism don’t all have trouble detecting the motion of people and animals. What they do struggle with is picking up social information from bodies in motion.

Even small head movements inside a brain scanner can affect results, according to a report published 23 July in Neuroimage.

The brains of teenagers with autism and their unaffected siblings respond similarly to both happy and neutral faces, whereas those of controls seem to prefer happy ones, according to a study published 12 July in Translational Psychiatry.

Children with autism often use the wrong pronouns, referring to themselves as ‘you’ in conversation. A new study shows that this difficulty in shifting perspective from other to self may result from impaired connections between brain regions.

Many toddlers with autism have weak connections between the two sides of the brain, according to the first-ever analysis of brain connections in young children with the disorder, published 23 June in Neuron.

The rapid brain growth seen in children with autism occurs early in life, before children reach 2 years of age, according to a study published in the May issue of Archives of General Psychiatry.

In the past year, several studies have suggested that brain scans will soon help clinicians diagnose autism. But many experts say these scans are far from — and may never be — ready for use as diagnostic tests.

A complex mathematical technique can improve the sensitivity of experiments that rely on brain imaging, allowing researchers to study how the brain responds to sequences of stimuli, according to a study published in the June issue of NeuroImage.

Smaller-than-normal volume in several brain regions, including a region involved in relaying motor signals, could be a marker for repetitive behavior in 3-year-old children, according to a study published 7 April in Autism Research.
