Resumen de Reawakening memories
Work by Christine Denny at Columbia University and her team suggests memories may not be wiped by Alzheimer's disease, but instead become harder to access. What's more, they can be artificially reawakened. The finding could be revolutionary, says Ralph Martins at Edith Cowan University in Australia. To examine how memory is affected by Alzheimer's disease, the researchers developed a way of visualizing individual memories in mouse brains. They genetically engineered mice so that neurons glowed yellow when storing a memory, and red when recalling one.
