Delta wave activity disruption during sleep may be a useful metric to identify those at an increased risk for cardiovascular disease and cardiovascular mortality. An international team of researchers ...

While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them. The brain collects far more memories than it can keep. We absorb new information throughout ...

If you've been looking for a sign to work on your sleep hygiene, this is it. A new study suggests that a particular wave of ...

Scientists have shown that delta waves emitted while we sleep are not generalized periods of silence during which the cortex rests, as has been described for decades in the scientific literature.

A sleeping rat may look peaceful. But inside its furry, still head, a war is raging. Two types of brain waves battle over whether the rat will remember new information, or forget it, researchers ...

When you sleep, your brain is taking all the information you learned during the day, and deciding what to do with it. Whether you remember that information, or lose it during the evening, could come ...

Distinct patterns of electrical activity in the sleeping brain may influence whether we remember or forget what we learned the previous day, according to a new study. The scientists were able to ...
