Sleep enhances memory with less energy, aiding Alzheimer's diagnosis

Summary: Researchers at UCLA discovered a brain mechanism enhancing memory formation while reducing energy consumption during sleep in the entorhinal cortex, crucial for learning and Alzheimer's onset. Using a novel mathematical model, they found a way to maintain memory states with less energy, potentially aiding early Alzheimer's diagnosis. The study, published in Nature Communications, reveals a new memory state called spontaneous persistent inactivity, doubling memory capacity while halving metabolic energy cost.
