A new government mandate requires researchers to include females in their animal studies — or explain why they don’t. What will this mean for autism research?
People with autism show abnormal brain responses when a painfully hot object is placed against their skin.
Girls with autism may show fewer repetitive behaviors than boys because of structural differences in brain regions that control movement.
A new questionnaire provides a standardized measure that allows researchers to reliably track repetitive and restricted behaviors over time.
An autism-linked mutation in the SHANK3 gene alters the protein skeleton of mouse neurons. Repairing the scaffold eases the animals’ social deficits.
The bundle of nerves that connects the brain’s two hemispheres is abnormally thick in infants who are later diagnosed with autism. The broader the bundle, called the corpus callosum, the more severe a child’s symptoms.
The social deficits and repetitive behaviors seen in boys with fragile X syndrome seem to stem from their cognitive difficulties, rather than arising independently as they do in autism.
