RNA bits vary in social, auditory brain areas in autism

by  /  14 November 2013

People with autism show differences from controls in the levels of microRNAs, small noncoding bits of RNA, in the social and sound-processing parts of the brain. Unpublished results from the postmortem study were presented Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.

Brain findings in autism leave researchers scratching heads

by  /  13 November 2013

Three decades of research on anatomical changes in the brains of individuals with autism has yielded few if any consistent patterns. The field needs an overhaul of the methods used, researchers said at a symposium Wednesday at the 2013 Society for Neuroscience annual meeting in San Diego.

Brain activity of microRNAs gives clues about autism

by  /  19 September 2013

Small regulatory RNA molecules are most active between infancy and early childhood in a region of the brain known for complex thinking and behavior, reports a new study published 6 August in Molecular Psychiatry. The finding, based on an analysis of postmortem brains, may provide insight into what goes wrong in neurodevelopmental disorders such as autism.

High-resolution model showcases brain anatomy

by  /  4 July 2013

Researchers have sliced a human brain into more than 7,400 slivers, and stained and scanned them to create ‘BigBrain,’ the most detailed three-dimensional map of a human brain to date, they reported 21 June in Science.

Postmortem brain analysis points to autism candidate genes

by  /  16 October 2012

An in-depth analysis of tissue from a large number of autism brains eases some of the qualms about their use in research, according to a poster presented Monday at the 2012 Society for Neuroscience annual meeting in New Orleans.

Loss of autism brain samples highlights need for donations

by  /  14 June 2012

A freezer malfunction that damaged a third of the largest collection of autism brain tissue points to the dire need for more donations, a better system for eliciting them, and a coordinated effort for storing and distributing tissue.

Gene expression altered in postmortem autism brains

by  /  23 April 2012

Postmortem brain tissue from people with autism shows differences in the expression of genes involved in a number of molecular pathways, including those that control cortical patterning, programmed cell death and differentiation, according to research published last month in PLoS Genetics.
