Researchers have mapped how immune cells in the brain called microglia change with age in mice.

Mutations in the Rett syndrome gene MECP2 have different effects on subtypes of neurons.

Spheres of brain cells derived from a fetal skull have gene expression patterns similar to those in brain tissue from the same fetus.

Sleep problems in autism may stem from the same biological changes that underlie the core features of the condition.

Differences in sleep and circadian rhythm may distort the results of autism studies.

Deleting FMR1, the gene mutated in fragile X syndrome, in subsets of mouse neurons leads to distinct features of the condition.

Neurons derived from people with a syndromic form of autism look and behave differently than do those from people with classic autism.

A different set of genes regulates brain activity in people with autism than the set involved in controls.

Introducing the gene UBE3A into neurons that dampen brain activity prevents seizures in a mouse model of Angelman syndrome.
