Technique follows calcium trail to track changes in signaling
Researchers have genetically engineered neurons to fluoresce in response to the calcium signals emitted when they fire, according to a study published 18 October in Neuron.

Drug improves social deficits in fragile X syndrome
A drug called arbaclofen improves behavioral problems in people with fragile X syndrome, an inherited condition that can lead to mental retardation and autism, according to the results of a clinical trial published today in Science Translational Medicine. A second study published in the same journal showed that the drug restores normal brain function in a mouse model of the disorder.

Autism-linked variants converge on two molecular patterns in mouse brains
Gene activity across 17 autism mouse models occurs in either of two opposing transcriptomic states, supporting the idea that diverse genetic changes may converge on a few recurring biological patterns.
