To understand the amygdala’s role in autism, researchers should study its connections with other brain structures and explore its role in development, says Ralph Adolphs.
When choosing whether to look at a face or an object, children with autism generally pick the same thing controls do, according to a study published 10 April in Frontiers in Psychiatry. The finding contradicts the widely held belief that people with autism tend not to look at faces.
Differences in brain activity that distinguish children with autism from controls may lessen with age, according to a meta-analysis published in the March issue of the Journal of the American Academy of Child and Adolescent Psychiatry.
Infants who are later diagnosed with autism are less attentive to the presence of a person onscreen at 6 months of age than their typically developing peers are, according to a study published 14 January in Biological Psychiatry.
Connections between neighboring groups of brain cells are weaker in individuals with autism than in controls, according to a report published 14 January in the Proceedings of the National Academy of Sciences.
Children with the autism-related disorder tuberous sclerosis complex show sluggish brain activity in response to images of faces, according to a study published 8 November in the Journal of Child Neurology.
Adults with autism are less specific and less reliable than controls at recognizing emotions from facial expressions, according to a study published 27 September in Neuropsychologia.
Early intensive therapy may normalize the brain’s response to faces in young children with autism, according to a study published in the November issue of the Journal of the American Academy of Child and Adolescent Psychiatry. The results are part of a randomized, controlled trial of a treatment called the Early Start Denver Model.
Family members of individuals with autism process faces and scenes differently than do controls, according to two new studies, one of them published in October. This suggests that visual processing may be an autism endophenotype — a measurable symptom that represents part of the genetic risk of a disorder.
