Brain circuit may permit scientists to eavesdrop on memory formation
... animals and then tested their ability to learn to navigate a tank full of opaque water to find a submerged platform. When the researchers tested the rats the day after the electrical lesions were made, they still recalled the platform's location. But they lost that memory four weeks after training. "There we...Evidence that learning is consolidated during sleep
