A new wiring diagram of the fruit fly brain is the most complex ever created.

A new technique allows researchers to transplant human microglia into mouse brains and better study the association between these cells and autism.

Injecting the gene-editing tool CRISPR into the brains of mice may reverse the effects of an autism mutation at any age.

Mice missing a copy of CHD8, a top autism gene, show a signaling imbalance in their brains — a finding in line with a popular hypothesis about autism’s origins.

Deleting the mutation from an autism gene may reverse some autism traits in mice, according to a new study. But the results may be a fluke.

Two new maps show the entire nervous system of the adult roundworm Caenorhabditis elegans.

Mutations in an autism gene called ANK2 may alter brain wiring by causing the growth of excess neuronal connections.

Brain tissues from people with autism of unknown cause and from people with either of two genetic forms of the condition all show similar patterns of methyl groups on DNA.

Two new resources may aid the study of synapses, the junctions between neurons.
