  • Brain waves called beta oscillations are more frequent and variable in children with autism than in those without the condition, says Gerardo Parra, who presented the unpublished work Thursday at INSAR 2023. A higher rate of beta oscillations tends to be associated with hyperreactivity to tactile stimuli, according to the analysis, which recorded the resting-state brain activity of 22 autistic and 27 non-autistic children.

  • An infant’s preference to look at faces over non-face objects is heritable, according to findings from an unpublished eye-tracking study of more than 500 5-month-old twins presented by Ana Maria Portugal Thursday at INSAR. A higher preference is also associated with greater verbal skills in toddlerhood, parent reports show. INSAR Abstract 306.002

Research roundup

  • Autistic youth are more likely than their non-autistic peers to have suicidal thoughts and to self-injure, according to a clinician rating scale; the findings are consistent with those derived from parent- and self-report questionnaires. Autism
  • Commonly used autism assessment instruments have good reliability, although subscales with fewer items, such as ones that measure restricted and repetitive behaviors, appear to be weaker than those with more items. Journal of Autism and Developmental Disorders
  • Autistic adolescents behave differently from their non-autistic peers in two classic economics games that assess sharing behaviors, according to a small study. Autism Research
  • The Repetitive Behaviors Questionnaire for Adults appears to be a valid measure of the four aspects of restricted and repetitive behaviors — repetitive motor movements, insistence on sameness, restricted interests and atypical sensitivity. Journal of Autism and Developmental Disorders
  • Drugs that promote myelination appear to mitigate electrophysiological and behavioral traits in a mouse model of Pitt-Hopkins syndrome. Brain
  • Integrating genetics with brain imaging and applying machine learning could reveal early biomarkers for autism, a review article suggests. Molecular Psychiatry
  • Different types of social interaction activate different regions of the brain with varying specificity. NeuroImage
  • Minimally verbal autistic toddlers speak more after one of two interventions targeted to their baseline traits and delivered over six months, according to a recent study. Autism Research

    Social perception: Functional magnetic resonance imaging maps people’s brain responses to seeing various social situations.

  • Autistic people do not seem to have a generalized downward gaze bias, which might otherwise explain why autistic people tend to gaze at other people’s mouths rather than at the eyes, according to a small study. Cognitive and Behavioral Neurology
