Cognition and behavior: Brain response to faces could signal autism

by  /  27 April 2011

At 12 months of age, infant siblings of children with autism have a brain response to unfamiliar faces that is characteristic of typical children at a younger age, according to a study published 26 March in Brain Topography. This developmental delay could be used as an early biomarker for autism.

Imaging biomarkers could signal autism spectrum disorder

by  /  12 April 2011

There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.

Machine-learning tool shows promise for autism diagnosis

by  /  14 March 2011

It’s too soon to call it a diagnostic test for autism, but an algorithm that detects patterns in brain waves shows promise as one component of a screening battery for the disorder, say researchers familiar with the work.

Brain-wave patterns bolster mouse models of autism

by  /  25 January 2011

Mice exposed to an epilepsy drug show several features of autism, including abnormal social interactions, repetitive behaviors and patterns of super-fast brain waves, called gamma oscillations, according to a study published 15 December in Biological Psychiatry.

High-tech national project set to trace brain’s connections

by  /  4 January 2011

Over the next five years, dozens of researchers funded by the $40 million ‘NIH Human Connectome Project’ will map the circuits of the human brain, tracing neural pathways and learning how different regions work together in synchrony.

Flow of water in the brain fingers autism

by  /  6 December 2010

An analysis of brain scans correctly distinguishes between people with autism and controls more than 90 percent of the time, according to a study published today in Autism Research.

Imaging study of autism finds imbalance of signals

by  /  18 November 2010

Children with autism have an imbalance of excitation and inhibition in the brain, according to the first study to measure synchrony between brain networks using magnetoencephalography (MEG). The findings were presented Wednesday at the Society for Neuroscience annual meeting in San Diego.
