Electrically stimulating a particular circuit in the brain shows promise for reversing symptoms of Rett syndrome, a disorder that shares features with autism.

A method that maps signaling molecules in the brain may help researchers home in on areas where seizures originate.

The mutation that leads to Angelman syndrome may affect the brains of female mice more severely than those of male mice.

Researchers have mapped the migration patterns of neurons in the developing monkey brain and pinpointed when they establish their identities.

A new drug that targets a molecule involved in learning reverses some cognitive difficulties in a mouse model of Rett syndrome.

Marijuana gets scrutiny as an autism treatment, and a new app may enable remote diagnosis of autism.

Researchers have discovered an enzyme that lowers brain levels of FMRP, the protein missing in people with fragile X syndrome. Blocking the enzyme may ease fragile X symptoms in people with the disorder who have low levels of FMRP and mild symptoms.

An autism-linked mutation in the SHANK3 gene alters the protein skeleton of mouse neurons. Repairing the scaffold eases the animals’ social deficits.

Children who are diagnosed with autism after drastically and suddenly losing cognitive abilities may actually have a distinct disorder, according to data presented yesterday at the 2015 International Meeting for Autism Research in Salt Lake City, Utah.
