![]() This busy neural activity is happening while you sleep, and it turns out that the processes can be influenced by what you hear during this period, even if you’re not consciously aware of it. So they actively replay, and it’s through this replay process that the information is redistributed from the hippocampus to more neocortical areas, which is where they’re stored long-term.” Chris DeGraw/Digital Trends, Getty Images ![]() “It’s then during sleep that the neurons, which represent the memory trace, seem to refire. When you learn a new piece of information, “it seems to be initially stored in the hippocampus, which is a deep brain structure,” Crowley said. So, sleep is important to help you learn, but can playing information out loud while you sleep be helpful to this process? The research done by Crowley and others suggests that it can due to the way language is processed in the brain. That equates to seven to 10 hours per night for most people, so don’t skip out on time in bed if you’re hoping to perform well at school. This is bad for your physical and mental health, as well as your ability to learn, so try to get a good night’s sleep as often as you can. ![]() School and college schedules can often be punishing, especially if you’re having to get up for early classes after staying up late working on assignments you may be chronically sleep deprived. Sleep deprivation also impairs the consolidation process mentioned above. ![]() When you’re sleep deprived, you struggle to focus and pay attention, and that means you’ll get less out of your lessons. You should also know that sleep is vital for good cognitive functioning overall. If you’re listening to something full of words you’ve never heard before, that probably won’t be helpful. “It seems like sleep plays a really crucial role in the consolidation phase of learning.” “Consolidation is about strengthening the information and integrating it into networks of information that already exist, for long-term storage,” Crowley said. The important differences between these stages for learning is that the non-REM and REM phases are when memories are consolidated. But Crowley says that dreams actually occur throughout all stages of sleep. You might have heard of REM sleep, which is when most people think that dreaming occurs. There’s a surface level of sleep, then two deeper levels that are divided into rapid eye movement (REM) and non-REM sleep. There are several stages of sleep, Crowley explains. It’s this process of moving a word from an episodic memory into the mental lexicon that seems to occur during sleep. This adds the word to what researchers call your mental lexicon, which is like an internal dictionary of words you know and their meanings. To really understand and use a new word, you need to link that word to other related words in the language. Genevieve Poblano/Digital Trends Graphics That means you remember the event of learning the word - where you were, who you were with, and so on. The research on exactly how language learning occurs is still ongoing, but current evidence suggests that when you learn a new word, you do so via what is called an episodic memory. Learning a language is a complicated psychological process. These headphones won’t just help you sleep better, they may help improve your memory ![]() Tired of nudging your snoring spouse?
