The case for using ‘prebiotics’

by ,  /  1 April 2014

Prebiotics — nutrients that promote the growth of some beneficial gut bacteria — can influence brain chemistry and behavior. New findings suggest prebiotics as treatments for people with neurological disorders, say Sarkis Mazmanian and Gil Sharon.

Cognition and behavior: Autism brains heightened to senses

by  /  17 January 2014

When exposed to irritating noises or images, children with autism show hypersensitivity in brain regions that process sensory information and emotions, according to a study published in November in the Journal of the American Academy of Child and Adolescent Psychiatry.

Compendium of mouse brains highlights autism’s diversity

by  /  14 November 2013

By mapping the brains of not 1 but 27 mouse models of autism, researchers are making sense of the widely divergent structural changes seen in autism brains, they reported 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.
