Mice missing a copy of the autism-linked gene NRXN1 appear to perceive some time intervals as shorter than control mice do, according to a new study.

Genes linked to autism are critical to the development of star-shaped brain cells called astrocytes, suggesting a key role for the cells in the condition.
Two researchers balk at talk that Wi-Fi and autism are linked, changes in an autism risk gene are tied to obsessive-compulsive traits in three species, and scientists plan to conduct a census of all of the brain’s cell types.
Having too many copies of an autism gene called UBE3A mutes a brain region that may mediate the satisfaction a person derives from social interactions.
The same autism-linked mutation can lead to dramatically different behaviors in rats and mice.
Researchers have for the first time isolated and characterized protein complexes found at the points of connection between neurons. Mutations in some of these proteins are linked to autism.
Researchers have developed a way to capture dynamic changes in the part of the neuron that sends out signals, they reported yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.
Mice that begin expressing a mutant version of a protein called neurexin at 2 weeks of age develop autism-like behaviors that researchers can erase weeks or months later. The report, published 24 July in Cell Reports, suggests that it may be possible to treat autism symptoms even in adulthood.
Differences in the background genetics of mouse strains may modify the effects of autism genes, suggests a study published 11 March in Autism Research. The study looked at the behavior of mice with a mutation in neuroligin-3, a strong autism candidate gene.
