A three-dimensional motion-capture system developed for film animation has found subtle differences in hip and ankle movement in children with autism compared with typically developing controls.
Two independent groups have created mice that have deletions or duplications in a large section of chromosome 16. Each team has produced an animal with a different set of features, some of which — such as large head size and repetitive behaviors — are reminiscent of people with autism.
Positive reinforcement can help children with autism break out of repetitive patterns of play. Results from a study broadly suggest that behavioral intervention can improve creativity in these children.
Deletion of the chromosomal region 17q12 dramatically increases the risk for autism and schizophrenia, according to a large study published last week in the American Journal of Human Genetics. Individuals missing this sizeable region are about 14 times more likely to develop one of those disorders, the study reports.
Children with autism show more activity in a brain region important for making decisions under changing circumstances, according to a poster presented Monday at the Society for Neuroscience annual meeting in San Diego.
An asocial inbred mouse strain called BTBR may show behaviors associated with autism, such as avoiding eye gaze and forming an attachment to objects, researchers reported Monday at the Society for Neuroscience annual meeting in San Diego.
The fruit fly is a good model for some of the cognitive defects in fragile X syndrome — but researchers sometimes find themselves having to defend their choice.
Blocking the expression of the MeCP2 gene decreases the number of synapses, the junctions between neurons. It also prevents synapses from scaling up their activity to make up for the loss, according to unpublished data shown yesterday at the Society for Neuroscience annual meeting in San Diego.
