Researchers have found that three different degenerative brain disorders are linked by a toxic form of the same protein. Elk-1 was found in clumps of misshaped proteins that are the hallmarks of Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease. This suggests a molecular link between the presence of inclusions and neuronal loss that is shared across a spectrum of neurodegenerative disease. Identifying these links could open up novel avenues for therapeutic intervention.

People with Parkinson’s disease suffer social difficulties simply because of the way they talk, a McGill University researcher has discovered. Marc Pell, at McGill’s School of Communication Sciences and Disorders, has learned that many people develop negative impressions about individuals with Parkinson’s disease, based solely on how they communicate. These perceptions limit opportunities for social interaction and full participation in society for those with the disease, reducing their quality of life.

New research shows our brains are a lot more chaotic than previously thought, and that this might be a good thing. Neurobiologists at the University of Maryland have discovered information about how the brain processes sound that challenges previous understandings of the auditory cortex, which had suggested an organization based on precise neuronal maps. In the first study of the auditory cortex conducted using advanced imaging techniques, Patrick Kanold, assistant professor of biology, Shihab Shamma, professor of electrical and computer engineering, and Sharba Bandyopadhyay, post-doctoral associate, describe a much more complex picture of neuronal activity.
