Paternal age drives ‘geek index’ scores, GWAS may have a big weakness, serotonin boosts mouse social behaviors, and what is science Tinder?

A new technique for building a ‘brain in a dish’ reveals how neurons move to their proper places during fetal development.

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.

Having too many copies of an autism gene called UBE3A mutes a brain region that may mediate the satisfaction a person derives from social interactions.

A drug used to treat excessive swelling seems to ease autism features in some children on the spectrum.

Removing the Rett syndrome gene, MeCP2, from distinct cells and brain regions reveals hidden features of the condition.

Using flashes of light, scientists can spark seizures, tweak cell junctions and motivate mice from afar.

Some mutations in a gene called SCN2A make neurons less excitable and are linked to autism; others have the opposite effect and may cause seizures during infancy.

Scientists have discovered more than 100 new proteins at junctions in the brain that dampen neuronal activity.

The brains of people with autism show a distinct molecular signature that reflects alterations in how genes are pieced together and expressed.
