It’s basically naptime for the nerve cells in yourbrainas you dip into non-REM sleep. They do send out a few messages, but nothing much. But like so many other bodily functions,brainactivity goes up during REM sleep, sometimes even more than during the day. Blood flow to thebrainand t...
During REM sleep, the brain hallucinates (i.e., dreams) in a paralyzed body, and the EEG activity recorded from the scalp resembles that seen during wakefulness.Atonia, or a complete loss of muscle tone, prevents us from acting our dreams and injuring ourselves du...
Siclari and her team have conducted this study to better understand what occurs in the brain during parasomnias. "It was commonly believed that dreams only occur in one sleep stage: REM sleep. We now know that dreams can happen in other phases too. Those who experience parasomnias during non...
Measuring someone’s brain activity during a parasomnia episode is no mean feat. The patient needs to fall asleep, experience an episode, and have their brain activity recorded while moving around. “There are currently very few studies that have managed to overcome this. But with the many elec...

comprises the majority of the cerebral cortex in the brain which plays a role in memory, thought, language and consciousness. In contrast during REM sleep, when most of our dreaming happens, neuronal firing is rapid and synchronised at much higher frequencies, between 30 to 80 times per second...
reality seems impossible? Well, you might have — in dreamland, that is. If you've ever noticed you're in a dream while it's actually happening, you're lucid dreaming. And here's what happens to your brain when you lucid dream that allows those sleep-time experiences to feel so real...
What happens to your memories while you sleep? As you slumber, the brain is a whir of activity sorting and storing your memories. How does it know which to choose, and how can you game the system? By Catherine de La...
Brain Activity When you close your eyes and start to drift into non-REM sleep, your brain cells settle down from their daytime activity levels and start firing in a steady, more rhythmic pattern. But when you start to dream, your brain cells fire actively and randomly. In fact, in REM ...
Scientists believe that during waking hours, our brains are ready to make or“ encode” new memories. But during sleep, our brains switch to consolidation mode. When you first learn something during the day, your brain lays down a“ memory trace.” Initially, this trace is particularly suscept...
