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.

Spectrum is covering the 2020 International SYNGAP1 Scientific Conference, which took place virtually because of the coronavirus pandemic. Here we’re highlighting researchers’ reactions to noteworthy presentations.

A new atlas lays bare how synapses, or the junctions between neurons, change from birth to old age in mice.

The overproduction of proteins in brain cells called microglia causes social impairments, cognitive deficits and repetitive behavior in male mice, a new study has found.

The mood-stabilizing drug lithium seems to ease repetitive behaviors seen in mice missing SHANK3, an autism gene.

Individuals with mutations in an autism gene called TRIO may have a range of conditions, including intellectual disability and anomalous head size.

A new wiring diagram of the fruit fly brain is the most complex ever created.

A new technique allows researchers to transplant human microglia into mouse brains and better study the association between these cells and autism.

Injecting the gene-editing tool CRISPR into the brains of mice may reverse the effects of an autism mutation at any age.

Mice missing a copy of CHD8, a top autism gene, show a signaling imbalance in their brains — a finding in line with a popular hypothesis about autism’s origins.
