The Brain and Sleep Spindles

Are you giving your brain enough rest? Rest is vitally important for memory and cognitive functions. Your brain is working for you when you're resting. New memories are only really useful if you can connect them to information you already know. A Harvard Medical School study identified a brain activity called Sleep Spindles: brief but intense bursts of brain activity that reflect information transfer between the hippocampus deep in the brain and the neocortex on the surface of the brain that apparently help to organize new memories and make vital connections with existing knowledge.
