Study Shows Where Alzheimer's Starts and How It Spreads
Using high-resolution functional MRI (fMRI) imaging in patients with Alzheimer's disease and in mouse models of the disease, Columbia University Medical Center (CUMC) researchers have clarified three fundamental issues about Alzheimer's: where it starts, why it starts there, and how it spreads. In addition to advancing understanding of Alzheimer's, the findings could improve early detection of the disease, when drugs may be most effective.

Study suggests we're all susceptible to false memories
Researchers have found that people with extraordinarily accurate memory are as vulnerable to the inception of fake memories as others, indicating that perhaps nobody is protected from memory distortion. The study, published last month in Proceedings of the National Academy of Sciences, focused on people with highly superior autobiographical memory, who are able to recall highly specific facts about their lives, like what they ate for lunch, going all the way back to their childhood.

Scientists solve 40-year mystery of how sodium controls opioid brain signaling
Scientists have discovered how the element sodium influences the signaling of a major class of brain cell receptors, known as opioid receptors. The discovery, from The Scripps Research Institute (TSRI) and the University of North Carolina (UNC), suggests new therapeutic approaches to a host of brain-related medical conditions.
