‘wake’ slow waves, employed by the brain to counteract epileptic activity. This mechanism takes advantage of protective brain activity that normally occurs during sleep, but, in people with epilepsy, can occur
CHARACTERISTIC patterns of brain waves can be recorded during various levels of sleep, normal or narcoleptic, and in coma or coma-like states. In short, any reduction of consciousness below the waking level is reflected in the brain wave pattern. The electroencephalogram is thus an ...
Stage 1 is the lightest stage of sleep where brain waves are beginning to slow down into alpha waves. This stage typically lasts only a few minutes and is easy to be woken from. Stage 2 continues the descent of brain waves towards theta activity, and lasts around 25 minutes. Your brain ...
People may count sheep when they cannot sleep, but when they do finally drift off their brains generate the same type of brain wave as their ovine counterparts, according to new research published ineNeuro. Monitoring how a sheep’s sleep changes during the progression of a brain disease may ...

There lies a paradox in sleep. Its apparent tranquility juxtaposes with the brain's bustling activity. The night is still, but the brain is far from dormant. During sleep, brain cells produce bursts of electrical pulses that cumulate into rhythmic waves—a sign of heightened brain cell function...
there's an overnight dialogue between the hippocampus—the brain's memory hub—and thecerebral cortex, which is associated with higher brain functions like reasoning and planning. This occurs during a phase of deep sleep, when brain waves are especially slow and neurons across brain regions altern...
(1 to 4Hz), and are associated with a state of drowsiness and sleep, respectively. These waves correspond to a slow depolarization of the neurons, unlike the rapid depolarization, which is associated with fast processing information during wakefulness. Alpha waves (8 to 13Hz) are associated ...
