New imaging techniques probe brain’s long-range connections

by  /  10 June 2013

New techniques to scan the brain can produce exquisitely detailed views of white matter, which contains the long cellular fibers that connect neurons. Many of the advances are emerging from the Human Connectome Project, a five-year push to map the brain’s wiring.

Imaging database catalogs brain connectivity

by  /  30 January 2013

Researchers can share and compare brain-imaging data on the UCLA Multimodal Connectivity Database, described in the 28 November Frontiers in Neuroinformatics. The resource builds connectivity matrices, which estimate the strength of connections between regions of the brain.

Autism risk gene found to alter brain wiring

by  /  13 September 2012

MET, a leading candidate gene for autism risk, influences the strength of connections between brain regions involved in social behaviors, and this effect is especially prominent in people with the disorder. The findings are from a large study using several imaging techniques, published 6 September in Neuron.

Cognition and behavior: Connectivity deficits link autism, TSC

by  /  7 August 2012

Abnormalities in the connections between language-related brain regions are similar in people with autism and those with tuberous sclerosis, a genetic disorder characterized by benign tumors throughout the brain and body, according to a paper published 1 June in Cerebral Cortex.
