New mouse model mimics many symptoms of autism

by  /  3 October 2011

Mice lacking the autism-linked gene CNTNAP2 show many of the behaviors associated with the disorder, and exhibit brain circuit disruptions similar to those seen in people who carry mutations in the gene.

Molecular mechanisms: Dopamine implicated in Rett syndrome

by  /  13 September 2011

Loss of MeCP2, the Rett syndrome gene, in neurons that release the chemical messenger dopamine may lead to the motor deficits associated with the syndrome.

Specialized neurons help explore circuit defects in autism

by  /  14 April 2011

A powerful cell that dampens electrical signaling in the brain could help unravel the disrupted brain wiring seen in people with autism, according to results presented yesterday at the Wiring the Brain meeting in Ireland.

Molecular mechanisms: Neuroligin-4 induces synapses in a dish

by  /  23 March 2011

Neuroligin-4, a protein associated with autism, is located at synapses — the junctions between neurons — that inhibit signals in the brain, according to a study published in February in the Proceedings of the National Academy of Sciences. The protein can also single-handedly induce neurons derived from human stem cells to form synapses, according to another study in the same issue.

Genetics: Rare mutation found in gene linked to autism

by  /  31 January 2011

Researchers have identified a rare genetic variant linked to autism in DLX1, a gene that regulates the growth of neurons, they reported in December in the American Journal of Medical Genetics.

Autism brains characterized by fewer excitatory neurons

by  /  16 November 2010

People with autism have structural differences in the temporal cortex — a brain region involved in sound and language processing — compared with controls, according to a postmortem study presented Monday at the Society for Neuroscience annual meeting in San Diego.

Researchers debut new mouse model for Rett syndrome

by  /  11 November 2010

A new mouse model for Rett syndrome shows that disrupting a single brain messenger can produce nearly all of the characteristic features of the syndrome, researchers report today in Nature.

Molecular mechanisms: Calming neurons have specific responses

by  /  26 October 2010

Most inhibitory neurons respond in the same way to a range of visual stimulation, but a subset of them may be tuned in to specific signals, suggest two reports published in September in Neuron.

Learning opportunities

by  /  23 March 2010

There are several short periods during development in which our brains are ‘plastic’ — meaning that neuronal connections appear and disappear depending on how much they are used. Researchers may have found a way to reopen those learning windows.
