Sentences with phrase «slow wave activity»

Importantly, this benefit of sleep on emotional attention regulation is specifically associated with slow wave activity.

Not exact matches

Punctuating REM are interludes of slow - wave sleep, a state in which brain activity ebbs and the waves become more synchronized.

After only getting half of a night's worth of sleep, the children showed more slow - wave activity towards the back regions of the brain — the parieto - occipital areas.

With a large number of electrode channels distributed across the scalp, this method also detects which brain regions show more slow - wave activity than others.

The findings suggest a link between the slowing of movement and greater beta wave activity seen in people with Parkinson's.

Slow - wave sleep is also the time when neurons rest and the brain clears away the molecular byproducts of mental activity that accumulate during the day, when the brain is busily thinking and working.

Slow oscillations in brain activity, which occur during so - called slow - wave sleep, are critical for retaining memorSlow oscillations in brain activity, which occur during so - called slow - wave sleep, are critical for retaining memorslow - wave sleep, are critical for retaining memories.

Yet average slow - wave activity was shallower in their left hemisphere during the first night — an asymmetry that was enhanced in those who took longer to fall asleep.

Based on anatomical sites with muted slow - wave activity, the researchers suspect the first - night effect involves the default - mode network, a system of interacting brain regions involved in daydreaming and spontaneous thoughts.

In deep, slow - wave sleep, recordings of the brain's electrical activity show sparse bursts of big, slow waves.

As participants slept, right hemisphere regions showed consistent slow - wave activity regardless of the night.

So - called unihemispheric sleep happens in animals when one side of the brain shows waking activity while the other side is asleep (an electroencephalographic recording of brain activity under these circumstances shows slow synchronous waves).

In humans, sleep is also characterized by brain activity: periods of slow - wave activity are each followed by short phases of Rapid - Eye - Movement sleep (REM sleep).

Another common feature with mammalian sleep was the coordinated activity of cortex with another area during slow - wave sleep: in dragons this other area is the so - called dorsal ventricular ridge.

In their report, Laurent and his colleagues describe the existence of REM and slow - wave sleep in the Australian dragon, with many common features with mammalian sleep: a phase characterized by low frequency / high amplitude average brain activity and rare and bursty neuronal firing (slow - wave sleep); another characterized by awake - like brain activity and rapid eye movements.

Until now, most sleep research has focused on global control of sleep, which occurs when the entire brain is awash in slow waves — oscillations of brain activity created when sets of neurons are silenced for brief periods.

Slow - wave sleep (SWS) is characterized by synchronized neural activity alternating between active upstates and quiet downstates.

Green and Arduini described an inverse relationship between hippocampal and cortical activity patterns, with hippocampal rhythmicity occurring alongside desynchronized activity in the cortex, whereas an irregular hippocampal activity pattern was correlated with the appearance of large slow waves in the cortical EEG.

In this region, apoE4 decreases two types of brain activity that are important for memory formation: sharp wave ripples (ripples) and coincident slow gamma activity.

Has anyone thought what propagates these waves (like is it dark matter or dark energy) and I wonder how much they affect the sun and earth - given they stretch / squeeze spacetime, could they slow the earth spin, flip poles, agitate fault lines as well as volcanic activity and heat up the sun causing more flares, etc..

In the third section of his talk (around 30 minute mark), Dr. McConnell discusses an experiment they are working on that uses EEG to monitor sleep, and according to their protocol, turn on a TES device (tACS - like) in order to induce slow wave EEG activity.

Within silico, a computational neural model was made to predict neural activity in slow - wave sleep.

These slow waves are called delta activity.

Drinking alcohol before bed is linked with more slow - wave sleep patterns called delta activity.

For example, in 1977 it was reported that electrical activity in the brains of pointer dogs showed the dogs went through cycles of REM and slow - wave or non-REM sleep just as we do.

Slowing such overturning by reducing the horizontal differential heating could tend to allow heat to build up at lower levels until the lapse rate is more favorable to localized vertical overturning (LVO)(The two forms of overturning are not always completely distinct or separate; for example, the Hadley cell, Walker, and monsoon circulations, as well as extratropical storm track activity (developing from baroclinic instability (Rossby wave phenomena)-RRB- are driven and organized in part by horizontal differential heating, but in the ascending portions of these circulations, cumulus - type convection can occur).
