Missing autism gene may affect time perception in mice

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.

Wi-Fi flap; obsessive-compulsive link; brain catalog and more

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.

Analysis of mouse brains maps subgroups of autism

A brain imaging study of 26 mouse models of autism reveals a broad range of structural abnormalities. The models cluster into groups with similar features, reports a study published 9 September in Molecular Psychiatry.

Mutant protein causes reversible autism-like behaviors

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.

Genetic background may alter behavior of autism mice

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.
