Surplus of neurons spurs autism traits in mice

by  /  15 January 2015

Fetal mice that have too many neurons grow to show social deficits and repetitive behaviors. The finding, reported 11 December in Cell Reports, debuts a mouse model of autism that’s based on a biological abnormality seen in some people with the disorder.

Autism-linked gene guides growth of subtype of neurons

by  /  19 November 2014

Mice missing PTEN, a strong autism candidate gene, in a subtype of inhibitory neurons in one part of the brain show signaling abnormalities and social deficits. Researchers presented the unpublished work yesterday at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Mimed gestures hint at repetitive behaviors in autism

by  /  15 November 2014

Children with autism show different patterns of brain activity during everyday gestures and movements than controls do, suggest unpublished results presented today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Signaling imbalance skews sensory responses in autism mice

by  /  11 August 2014

Mice modeling autism have trouble integrating different kinds of sensory information such as sight, sound and touch. A study published 31 July in Neuron reports that an imbalance between signals that calm neurons and those that excite them leads to these sensory problems.

How to evaluate new medications for autism

by  /  10 June 2014

There are no available medications for treating autism’s core symptoms, but there are several candidates in clinical trials. Jeremy Veenstra-VanderWeele describes the factors researchers must take into account when developing drugs for the disorder.

Neurons that inhibit brain signals are key in Rett syndrome

by  /  5 May 2014

Deleting MeCP2 from a subset of neurons that mediate inhibitory signals recapitulates many of the symptoms of Rett syndrome in mice. Conversely, expressing the gene only in that subset, but not in the rest of the brain, protects the mice from some of those same symptoms. The results were published last week in Nature Neuroscience.

High-throughput screen finds genes that link neurons

by  /  30 April 2014

A new algorithm allows researchers to search among hundreds of genes and identify those involved in building synapses, the junctions that transmit signals between neurons, according to a report published 14 March in PLoS One.
