Tracking neurons’ long projections to unravel autism

by ,  /  21 October 2014

Many brain imaging studies of autism focus on neurons’ connections or activity, but examining neuronal tracts across the brain is equally informative, say Julia Owen and Pratik Mukherjee.

Method reveals relationship between white, gray matter

by  /  27 August 2014

A new technique helps researchers trace the nerve fibers that connect brain regions by revealing how the fibers physically relate to curves and folds on the brain’s surface. The method was described 8 July in Medical Image Analysis.

The cerebellum’s surprisingly evolved role in autism

by  /  1 April 2014

Thought until recently to only coordinate motor skills, the cerebellum is involved in diverse cognitive functions such as language and social interaction, and may play a role in autism, says Emanuel DiCicco-Bloom.

Charting typical brain development

by  /  20 December 2013

How can we characterize what is atypical when we don’t fully understand what typical brain development looks like, particularly under the age of 5? Christine Wu Nordahl explains the importance of scanning the brains of typically developing children.

Close look at autism-linked region reveals complex biology

by  /  27 November 2013

Deletion and duplication of the 16p11.2 chromosomal region have opposite effects on brain size, but produce similar alterations in the brain’s processing of sound. Researchers reported these and other unpublished findings at the 2013 Society for Neuroscience annual meeting in San Diego, painting a complex picture of the region’s role in autism.

Cognition and behavior: Autism traits predict connectivity

by  /  14 June 2013

People who show strong autism traits tend to have weak connections between an area of the brain involved in introspection and social memories and other brain regions, according to a study published 5 April in PLoS One.

What can studying white matter reveal about autism?

by  /  10 June 2013

Advanced imaging techniques may reveal more precise pictures of how of the brain’s regions communicate with one another. How much of the neurodevelopmental riddle of autism lies in these tracts?
