Sentences with phrase «during sleep spindles»

Not exact matches

Sleepers who tolerated louder sounds before waking showed a higher frequency of «sleep spindles» — short bursts of activity of specific wavelength — during non-REM sleep than those who woke more easily.

While these brain rhythms, occurring hundreds of times a night, move in perfect lockstep in young adults, findings published in the journal Neuron show that, in old age, slow waves during non-rapid eye movement (NREM) sleep fail to make timely contact with speedy electrical bursts known as «spindles.»

Scientists speculated that these spindles shut out environmental sounds during sleep.

Now we know that during spindles, specific pathways are activated in dendrites, maybe allowing our memories to be reinforced during sleep.

«Our data suggest that spindles facilitate processing of relevant memory features during sleep and that this process boosts memory consolidation,» Staresina says.

But many questions about the link between sleep spindles and reactivated memories during sleep remained.

During slow - wave sleep, groups of neurons firing at the same time generate brain waves with triple rhythms: slow oscillations, spindles, and ripples.

In contrast, sleep spindles did not occur during high frequency stimulation.

Here, we show that spindles increased shortly after sound cues presented during sleep to promote replay.
