Non-rapid eye movement (NREM) sleep is characterized by three patterns of rhythmic brain activity: hippocampal sharp-wave ripples, thalamic spindles and slow cortical oscillations. Phase-locked ...

Biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one ...

While we sleep, the brain produces particular activation patterns. When two of these patterns - slow oscillations and sleep spindles - gear into each other, previous experiences are reactivated. The ...

Manipulating the pulses of electrical activity in the thalamus during non-REM deep sleep make mice remember or forget. Have you ever tried to recall something just before going to sleep and then wake ...

While we sleep, the brain produces particular activation patterns. When two of these patterns - slow oscillations and sleep spindles - gear into each other, previous experiences are reactivated. The ...

Every night while you sleep, electrical waves of brain activity circle around each side of your brain, tracing a pattern that, were it on the surface of your head, might look like the twin hair buns ...

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 ...

Have you ever tried to recall something just before going to sleep and then wake up with the memory fresh in your mind? While we absorb so much information during the day consciously or unconsciously, ...
