Corpus callosum ages abnormally in autism

by  /  10 April 2015

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.

Noisy patterns of connectivity mark autism brains

by  /  29 January 2015

A new study may have solved a decade-old debate about whether the brains of people with autism are more or less connected than those of controls: They’re both, depending on where in the brain you look.

Diffusion imaging of human connectome doesn’t hold water

by  /  23 December 2014

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.

Mimed gestures hint at repetitive behaviors in autism

by  /  15 November 2014

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with autism show different patterns of brain activity during everyday gestures and movements than controls do, suggest unpublished results presented today at the 2014 Society for Neuroscience annual meeting in Washington, D.C.

Method reveals thin insulation on neurons in autism brains

by  /  24 September 2014

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.

Autism, attention deficit marked by opposing brain changes

by  /  9 September 2014

A brain hub responsible for higher-order tasks may be overly connected in autism and thinly connected in attention deficit hyperactivity disorder.

Active or at rest, brain conducts similar symphonies

by  /  5 August 2014

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.

Researchers unveil fetal brain map, mouse ‘connectome’

by  /  17 April 2014

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.

Scarcity of brain’s immune cells alters mouse behavior

by  /  13 February 2014

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.
