Let Sleeping Dogs Lie: It Helps Them Consolidate Memories
Want to teach an old dog new tricks? Try letting your pet take a nap. New research finds that dogs consolidate new memories in sleep, just like humans do. The study used electroencephalography (EEG), a technique that measures electrical activity in the brain via the scalp, to track snoozing dogs' brain activity. Similar to humans, the dogs showed short bursts of activity, called sleep spindles, during non-rapid-eye-movement sleep. Also as in humans, the frequency of these sleep spindles was linked to how well a dog retained new information it had learned before its nap.
