The steady sequence of failed clinical studies in Alzheimer's has underscored just how much researchers in the field have to learn about the science of forming and retaining memories. Now a group at Johns Hopkins says it has a tool for brain research that could illuminate some of the dark alleys in the science. Using specially designed mouse models, they were able to track how the position of certain proteins changed as memories were formed. And perfecting this approach could help advance new research into Alzheimer's, autism, schizophrenia and other disorders of the brain. Release | Video
