Sensitive test of autism treatment effects could enable comparison of different interventions
In a first, researchers used the BOSCC measure to analyze data from multiple previous studies.

Autism-linked genes shape touch processing through different mechanisms, at different times
Whereas some mice display hypersensitivity to touch only as adults, others respond that way from birth.

Making cancer nervous
Nerve cells in the brain and throughout the body can turbocharge tumor growth — a finding that not only expands conventional ideas about the nervous system but points to novel therapeutic targets for a range of malignancies.
Lacking autism-linked gene, female birds tune out favorite songs
The gene, FOXP1, influences an animal’s motivation to listen to social communication, a new study suggests.

On the periphery: Thinking ‘outside the brain’ offers new ideas about autism
Neuronal alterations outside the brain may help to explain a host of the condition’s characteristic traits, including sensory changes, gut problems and motor differences.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
