An influx of $4.5 billion from the federal government over the next 12 years could jump-start a new generation of technologies, including tools for autism research.

A new imaging technique can capture the activity of every neuron in a zebrafish larva or a roundworm. Researchers described the method, which is at least ten times faster than others, in Nature Methods.

Taking a page from astronomy’s playbook, researchers have developed a way to take dramatically clear pictures of the inner workings of a zebrafish brain.

The cortex, the outer layer of the brain, grows rapidly in early childhood in people with autism and thins differently with age than it does in controls, two new studies report.

A teenage girl with Rett syndrome has a mutation in WFR45, a gene that is mutated in people who abruptly lose motor and mental skills in adulthood, according to a study published 13 March in the Journal of Human Genetics.

A new method for turning brains transparent and scanning them will make it easier to map neuronal circuits, according to a paper published 24 April in Cell.

Male and female preschoolers with autism have distinct sets of brain regions that distinguish them from typically developing controls, according to unpublished research presented Saturday at the 2014 International Meeting for Autism Research in Atlanta.

A Swedish twin study plans to search for the shared genetic and environmental origins of autism and attention deficit hyperactivity disorder, which are often mistaken for each other.

Proteins that help guide neurons to their correct destination in the brain may be involved in autism, says Christopher Cowan.

Roughly one-third of children with fragile X syndrome also have an autism diagnosis. Studies published in the past few months, however, suggest that the set of autism-like symptoms seen in people with fragile X syndrome may only resemble autism superficially.
