How Episodic Memories Form and Develop George Dragoi, MD, PhD , associate professor of psychiatry and of neuroscience at Yale School of Medicine, studies how episodic memories—memories of specific events or experiences—form and develop.

Phase 1: Memory Encoding During encoding, the brain samples stimuli from the outside world and rapidly encodes them within sequences inside networks of neurons in the hippocampus. Phase 2: Memory Consolidation In consolidation, a process that researchers think occurs during sleep, particularly slow-wave sleep, encoded sequences are integrated by chemical connections into new and existing neuronal knowledge networks and filed for long-term storage in the neocortex.

University of Utah Health scientists working in collaboration with an international team of researchers have found that memory consolidation can be boosted with sensory stimulation during sleep—and it has big implications for all kinds of future studies.

We wanted to use this study to understand the brain processes that support memory reactivation. Albouy decided to study this phenomenon with postdoctoral scientist Judith Nicolas, PhD, and their colleagues at KU Leuven, a research university in Belgium.

Albouy is now continuing the research at the University of Utah. The study appears in eLife , a peer-reviewed, open access scientific journal. The new research builds on previous work that suggested that both animal and human brains reactivate newly learned material during sleep, in the same part of the brain that was activated during initial learning.

They had the participants learn two different piano tasks and played auditory cues at the same time. After learning the tasks, participants were offered the opportunity to take a minute nap in the sleep lab. To remember information, you need to pay attention to it.

If you're tired, you simply cannot pay attention as effectively as you would if you were well rested. That statement seems straightforward, but it brings up another question: why do you get tired?

You may feel tired and have trouble paying attention either because you've been awake too many hours and sleep pressure is building up, or — even if you've had a nap — because it is the middle of the night and your circadian rhythm your internal clock is telling you to sleep.

In either case, you'll you have trouble paying attention, and thus trouble remembering. Caffeine blocks chemical receptors in your brain so that, temporarily, you cannot feel the sleep pressure.

Thus, caffeine can enable you to be more alert, be more attentive, and remember better. But as you probably know from your own experience, caffeine can only delay the mounting sleep pressure, which eventually leads to overwhelming tiredness. When you learn new information during the day, it is temporarily stored in the hippocampus , a seahorse-shaped part of your brain behind your eyes.

The hippocampus has a limited storage capacity. If you exceed it, you may have difficulty adding new information — or you may actually overwrite an old memory with a newer one. Fortunately, that doesn't usually happen. Each night while you sleep, the connections between neurons called synapses shrink to reduce or eliminate the memories you don't need — such as what you ate for breakfast last week and the clothes you wore yesterday.

This selective pruning of synapses during the night prepares you to form new memories the next day. Sleep also helps us consolidate the memories we want to preserve, transferring them from transiently accessible memories to those that can be recalled years later. Memories for facts and skills both show greater retention over a hour period that includes sleep versus a hour period while awake.

Much of this consolidation occurs during stage 2 sleep, a light sleep phase that occurs most in the hours prior to awakening. This means that if you get up early without a full night's rest, you may be impairing your ability to hold onto your memories.

Although you dream in several stages of sleep, your most interesting and vivid dreams usually occur during rapid eye movement REM sleep, so-called because while your eyes are moving rapidly, your body is otherwise paralyzed.

It is during REM sleep that your newly consolidated memories become interconnected with your prior memories, including those of your life as well as your library of facts and knowledge.

This connection between your recent memories and your prior memories and knowledge is one reason that you may wake up with a new and valuable perspective on a problem — or perhaps even a complete solution!

This actually happened to Dmitri Mendeleev , who was struggling for months with how the atomic elements should be placed in the periodic table. In a dream on February 17, , he glimpsed where all the elements belonged and, after writing down what he dreamt, found only a single, small correction was needed.

Have you ever been terribly upset about something and, by the next day, it felt at least somewhat better? Sleep can also strip off the emotions related to painful memories while still retaining the memory content. Thus, you'll be able to remember what upset you without having to relive the full emotional intensity of the event.

Melatonin isn't a traditional sleeping pill, but it can help regulate your sleep cycle if that's the problem. Acetaminophen can relieve little aches and pains that can keep you up at night. All other sleeping pills, however, whether prescription or over the counter, sedate you and actually make your memory worse, both for what you learned earlier that day and what you're trying to learn the next day!

Nonpharmacological treatments for sleep are by far the best.
