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.

Exclusive: Recruitment issues jeopardize ambitious plan for human brain atlas
A lack of six new brain donors may stop the project from meeting its goal to pair molecular and cellular data with the functional organization of the cortex.

The brain’s quiet conductor: How hidden cells fine-tune arousal
New research published today suggests that the pericoeruleus acts as a kind of micromanager of arousal, selectively inhibiting different subgroups of locus coeruleus neurons depending on the behavioral context.
