How Sound Affects Our Memories While We Sleep
Neuroscientist Greg Gage discusses an incredible experiment that shows how we can learn while we sleep. Scientists believe that when we are in our deepest phase of sleep, called slow-wave sleep, we transfer short-term memories into long-term memories. To test this theory, scientists cued sounds associated with a memory game into people’s headphones while they were in slow-wave sleep. When they woke up, they matched the memory game pictures associated with cued sounds better than the others, despite the fact that they had no memory of hearing them.
