Autism is predominantly genetic in origin, but a growing list of prenatal exposures for mother and baby may sway the odds.
Charting the structure and function of the brain’s many circuits may unravel autism’s mysteries.
Children who have repetitive behaviors, a core autism trait, may show particular patterns of brain activity as early as 1 year of age.
Autistic children aged 2 to 4 have about 15 percent more fluid between their skull and their brain than their typical peers do.
A new database displays gene-expression patterns in individual cells of the developing mouse cerebellum over time.
The autism gene TBR1 controls the expression of several other candidate genes that govern the architecture of the brain’s outer section.
A protective molecular tag on neurons can prevent microglia, the brain’s immune cells, from trimming away their connections with other neurons.
Lattice-like structures that surround neurons may be overly abundant — or scarce — in brain regions of three autism mouse models.
