Brain scans of babies reveal how nerve tracts mature

by  /  13 May 2017

Bundles of nerve fibers that bridge brain areas develop rapidly during the first six months of life. Fibers that connect language regions mature more slowly than those linking motor regions.

Thick bridge of nerves may signal autism in infancy

by  /  4 June 2015

The bundle of nerves that connects the brain’s two hemispheres is abnormally thick in infants who are later diagnosed with autism. The broader the bundle, called the corpus callosum, the more severe a child’s symptoms.

Brain structure abnormalities predict repetitive behaviors

by  /  19 May 2015

Among babies who go on to receive a diagnosis of autism at age 2, alterations in brain structures forecast the severity of repetitive behaviors. The preliminary results were presented Saturday at the 2015 International Meeting for Autism Research in Salt Lake City, Utah.

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.
