New technique prepares mouse brains for mapping

by  /  28 November 2012

Researchers have developed a method to fix and stain intact mouse brains for electron microscopy, according to a study published 21 October in Nature Methods. The technique allows them to trace the paths of neurons as they project across the brain.

Molecular mechanisms: Autism protein connects neurons

by  /  28 November 2012

An autism-linked protein called CASPR2 promotes the development of dendrites, the bushy structures atop neurons that receive signals from other neurons, according to a study published 30 October in Proceedings of the National Academy of Sciences. Lowering CASPR2 levels leads to sparse dendrites and few synapses, the junctions between neurons.

Virtual brain suggests neural connections form randomly

by  /  7 November 2012

Researchers are assembling a virtual reconstruction of the brain by piecing together simulations of thousands of neurons, they reported 16 October in the Proceedings of the National Academy of Sciences. They used this model to show that most junctions between neurons form randomly and not as the result of chemical signals.

Placenta plays potent role in autism risk

by ,  /  2 October 2012

As the central organ regulating maternal-fetal interactions, the placenta is perfectly positioned to mediate environmental and genetic risk factors during prenatal development. It may also relay risk factors for autism to the fetus, says Paul Patterson.

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.
