Mice reveal roots of sensory issues tied to top autism gene
Mice with mutations in the autism-linked gene SYNGAP1 have trouble sensing touch, which may stem in part from brain-circuit alterations and dulled alertness.

Autism unsurprised; diagnostic camouflage; Neanderthal legacy and more
People with autism aren’t easily surprised, the social camouflage some girls and women with autism use may preclude diagnosis, and autism-related genes are rooted deep in human ancestry.

Delayed pupil response to light may be early sign of autism
The pupils of preschoolers with autism are slow to constrict in response to light, a phenomenon that may serve as an early marker of autism risk.

Shrinking pupils may mirror autism risk in babies
The pupils of 10-month-old infants who have a sibling with autism constrict unusually fast in response to flashes of light, hinting that this reflex could be an early sign of the disorder.

Controversial study uncovers hearing glitch in autism
An ear muscle is more sensitive to loud sounds in children with autism than in controls, according to a study published 3 July in Autism Research. The researchers say this measure could serve as a clinical biomarker of the disorder, but others fiercely disagree.

Study links pupillary reflex, heart rate in autism
More than half of children with autism have a delayed pupillary response to light, along with a high heart rate and other physiological features, according an unpublished study presented Thursday at the 2013 International Meeting for Autism Research in San Sebastián, Spain.

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.
