The thick bundle of nerve fibers that links the left and right hemispheres of the brain develops differently in children with autism, a nine-year study has found.

The colorful brain maps created with diffusion imaging — a technique that uses the flow of water as a proxy for nerve tracts — are unlikely to represent the brain’s anatomy with accuracy, says a new study.
Children with autism show different patterns of brain activity during everyday gestures and movements than controls do, suggest unpublished results presented today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.
A method for measuring myelin, the protective sheath around neurons, indicates that there is less of it in the brains of people with autism than in those of controls.
A brain hub responsible for higher-order tasks may be overly connected in autism and thinly connected in attention deficit hyperactivity disorder.
Researchers measure how brain networks work together by scanning volunteers’ brains either while they’re resting passively or while they’re engaged in a task. A study published 2 July in Neuron argues that the networks activated in these two scenarios are more similar than previously thought.
Two new maps of the brain — an atlas of fetal development and a wiring diagram in the mouse — debuted 2 April in Nature. The maps may open new avenues of investigation into the genetic and neurological basis of autism.
A temporary shortage of microglia — immune cells in the brain that prune unnecessary neural connections — in infancy can have long-lasting effects on brain circuits and behavior, according to a study published in Nature Neuroscience on 2 February.
