David and Bernardo Sabatini, brothers born just a year and a half year apart, invent their way to answering big questions about autism.

Deleting one copy of a gene called MVP impairs the brain's ability to adapt to changes in the environment.

Male mice with a genetic variant tied to autism may have learning difficulties that females with the variant do not.

Researchers have used transcranial magnetic stimulation to show that people with fragile X syndrome have weak ‘inhibitory’ signals, those that dampen neuronal activity in the brain.

RNA segments that control when and where genes are expressed may be involved in autism.

Pups born to pregnant mice infected with a mock virus are known to show changes in their immune system. These effects may in turn impair proper brain signaling, according to results presented Saturday at the 2013 Society for Neuroscience annual meeting in San Diego.
