An online map of the marmoset brain may enable researchers to better understand how neuronal connections function.

Researchers have used the gene-editing tool CRISPR to disable the MECP2 gene in marmoset embryos. The six such marmosets created seem to recapitulate aspects of Rett syndrome.

A new free online library contains a vast assortment of digitized macaque brain slides.

Marmosets exposed to a mock infection in the womb have altered vocal development and diminished social interest; exposed macaques show changes in brain structure and function.

Researchers have engineered two generations of monkeys with mutations in SHANK3, a top autism gene. The first generation shows traits reminiscent of the condition.

Scientists have created five monkey clones, all carrying an edit to a specific gene.

This year’s list of top papers highlights new dimensions in our understanding of autism genetics and hints at novel treatments.

The first monkey with a mutation in SHANK3, a top autism gene, is nearly 3; it spends its days circling its cage rather than interacting with other monkeys.

After the presentation of more than 14,000 abstracts over five days, the Society for Neuroscience annual meeting in San Diego ended last week.

Scientists used the gene-editing tool CRISPR to create two marmosets lacking MECP2, the gene mutated in Rett syndrome.
