The common belief that people with autism look at people’s mouths instead of their eyes is inaccurate and has little evidence, say Nouchine Hadjikhani and Quentin Guillon.
Genetic variants in a receptor for the hormone oxytocin may contribute to the range of social skills seen in individuals with and without autism, suggests a study published 4 February in the Proceedings of the National Academy of Sciences.
Three studies published over the past two months have found significant evidence that children and adolescents with autism have brains that are overly connected compared with the brains of controls. The findings complicate the theory that autism is fundamentally characterized by weakly connected brain regions.
A subset of neurons in the amygdala is dedicated to recognizing eyes. But in people with autism, they may respond instead to the mouth, according to a report published 20 November in Neuron.
Conventional wisdom about how men and women process images of faces may be wrong, with significant implications for autism research, suggests an analysis of unpublished brain imaging data presented at the 2013 Society for Neuroscience annual meeting in San Diego.
Three decades of research on anatomical changes in the brains of individuals with autism has yielded few if any consistent patterns. The field needs an overhaul of the methods used, researchers said at a symposium Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.
Two studies published in the past few months suggest that face-processing deficits in people with autism are complex and may depend on the task.
Baby boys later diagnosed with autism lose interest in other people’s eyes between 2 and 6 months of age, according to a study published today in Nature. This is the earliest behavioral marker of autism found to date.
Infants later diagnosed with autism tend to look at the hair and body of someone speaking to them instead of at the eyes and mouth, which convey social cues, reports a study published 13 August in Biological Psychiatry.
