Penn study shows why sleep is needed to form memories. PHILADELPHIA – If you ever argued with your mother when she told you to get some sleep after studying for an exam instead of pulling an all-nighter, you owe her an apology, because it turns out she's right. And now, scientists are beginning to understand why.
In research published this week in Neuron, Marcos Frank, PhD, Assistant Professor of Neuroscience, at the University of Pennsylvania School of Medicine, postdoctoral researcher Sara Aton, PhD, and colleagues describe for the first time how cellular changes in the sleeping brain promote the formation of memories. "This is the first real direct insight into how the brain, on a cellular level, changes the strength of its connections during sleep," Frank says.
The findings, says Frank, reveal that the brain during sleep is fundamentally different from the brain during wakefulness. "We find that the biochemical changes are simply not happening in the neurons of animals that are awake," Frank says. A molecular explanation is emerging. Dreams.
Lucid dreaming is the experience of being completely aware within a dream that you are, in fact, in a dream. This realization leads to complete power for the dreamer, allowing him/her to go anywhere and do anything in their dream. You might have had this happen to you once or twice in your life, but chances are the dream didn’t last very long.
This is because as soon as people get excited from realizing they have achieved lucidity, they tend to wake up. So how does one avoid this problem, or even have more consistently lucid dreams in the first place? 1) Master Dream Re-Call Before you can lucid dream, you have to be able to remember that dreams that you have so that you can improve your technique. Second, figure out your method for recording your dreams when you do remember them. 2) Carry Over Some Consciousness Pick a night when you are so tired that you will fall asleep as soon as you hit the bed…but don’t. 3) Reality Checks 4) Final Tips. Alternate Sleep Cycles.
Most people only think that there is one way to sleep: Go to sleep at night for 6-8 hours, wake up in the morning, stay awake for 16-18 hours and then repeat.
Actually, that is called a monophasic sleep cycle, which is only 1 of 5 major sleep cycles that have been used successfully throughout history. The other 4 are considered polyphasic sleep cycles due to the multiple number of naps they require each day. How is this possible? How is this healthy? Well the most important of every sleep cycle is the Stage 4 REM (Rapid Eye Movement) sleep, which has been shown to provide the benefits of sleep to the brain above all other stages of sleep.
