Ready or not, here come genetic tests for autism
Late in June, an announcement appeared on the website of GeneDx, a genetic testing company based in Gaithersburg, Maryland. It was highlighted in red with a single word: “new”.

The case for copy number variations in autism
Following a series of papers in the past two years, what seems irrefutable is that copy number variations ― in which a particular stretch of DNA is either deleted or duplicated ― are important in autism.

Mouse models for autism debut
Two research groups have achieved an elusive goal: producing mouse models that show distinct social and behavioral abnormalities reminiscent of autism.
MEG imaging simplifies mapping of autistic brains
Imagine being confined for at least half an hour to a dark, claustrophobic tunnel, in a machine so obnoxiously loud that it sounds like you're in an oil drum with a jackhammer pounding on the outside. Thatʼs whatʼs involved in magnetic resonance imaging (MRI): an experience enough to make even the bravest among us flinch.

Changes in chromosome 16 firmly linked to autism
In a paper published today in The New England Journal of Medicine, researchers have identified a segment containing 25 genes on chromosome 16 that was deleted or duplicated in roughly one percent of children with autism.

The visual system’s lingering mystery: Connecting neural activity and perception
Figuring out how the brain uses information from visual neurons may require new tools. I asked 10 neuroscientists what experimental and conceptual methods they think we’re missing.

Boosting SCN2A expression reduces seizures in mice
A modified form of CRISPR amps up expression of the gene—a strategy that could apply to other gene variations linked to autism.
