New magnetic resonance imaging techniques allow brain maps of live humans to be constructed. So scientists can now investigate how neurological disorders, such as Parkinson's disease, Alzheimer's disease and schizophrenia change the wiring in the brain. Crofts and Higham at the University of Strathclyde looked at brain networks of patients who had suffered strokes. They introduced a new concept called `weighted communicability', which measures the way information spreads around the brain. Their research showed that stroke patients can be distinguished through an overall decrease in communicability, and also revealed the brain regions where communicability is most likely to break down.
