The brain's activity patterns at rest, when no mental task is challenging the brain, differs between healthy brains and those harboring diseases such as Parkinson's and Alzheimer's disease. A recent imaging study by Spetsieris et al. in the journal, the Proceedings of the National Academy of Science, highlights such differences and discusses how these brain activity signatures could be used to help diagnose or develop treatments for such widespread and debilitating diseases.
