Sentences with phrase «slow oscillations in»

Although there were a few earlier hints, the first clear description of regular slow oscillations in the hippocampal EEG came from a paper written in German by Jung and Kornmüller (1938).

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

Using The Reference Station Method (a Hansen invention) will also be hobbled by an unrecognized slow oscillation in the hemispheres as the «baseline» relationship between thermometers will not match the «later» relationship.

Not exact matches

The two frequencies alternated every 40 seconds, reminding Laurent of the regular oscillations between high - frequency REM and slow - wave sleep found in mammals and birds.

It converts the rapid oscillation of the optical laser light wave into a fluctuation in the laser intensity that is precisely a factor of one million slower.

In April 2008, scientists at NASA's Jet Propulsion Laboratory announced that while the La Niña was weakening, the Pacific Decadal Oscillation (PDO)-- a larger - scale, slower - cycling ocean pattern — had shifted to its cool phase.

Researchers found that some of these oscillations are linked with blood pressure, but are generally slower, occurring at lower frequencies, which have been shown in previous studies to be related to oscillations in vascular motion and blood oxygenation.

When the volunteers were exposed to stimulating sounds that were in sync with the brain's slow oscillation rhythm, they were better able to remember word associations they had learned the evening before.

«Importantly, the sound stimulation is effective only when the sounds occur in synchrony with the ongoing slow oscillation rhythm during deep sleep.

Predictions of global cooling in the short term are partly based on the idea that sea surface temperatures will fall in the northern Atlantic, due to slow, irregular swings in conditions known as the Atlantic Multidecadal Oscillation.

«The slow oscillations probably drive a replay of recently encoded memories in the hippocampus, where the declarative memories are temporarily stored,» Marshall says, referring to the type of memory used to recall facts and events consciously.

«Often during the night a regular pattern is manifested, where a slow oscillation from the cortex is immediately followed by a thalamic spindle and while this happens, a hippocampal ripple appears in parallel.

The first group received the light input just after the slow oscillations, so their spindle could form a triple rhythm (in phase): slow oscillation - spindle - ripples.

This is the first study to show that artificial thalamic spindles affect memory, if administered in sync with slow oscillations.

Slow oscillations originate from neurons in the cerebral cortex.

In doing so, Daya Bay researchers searched for a faster, smaller oscillation imposed on top of the longer, slower one that accounts for the disappearance of electron neutrinos from the sun, which is dominated by a different mixing angle.

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.

In the present study, we directly tested this idea by using an open - loop real - time algorithm to deliver auditory cues to sleeping subjects at these hypothesized optimal and suboptimal slow - oscillation phases.

Again, I think there is incontrovertible evidence that the AMOC slowed down after the mid 90's when the intense storms and a strongly positive North Atlantic Oscillation led to the strongest AMOC in decades.

In rats, the slowest movements give rise to frequencies around 6.5 Hz, the fastest to frequencies around 9 Hz, although faster oscillations can be observed briefly during very vigorous movements such as large jumps.

These results suggest that the verbal disorder in autism could be associated with an altered balance of slow and fast auditory oscillations, and that this anomaly could compromise the mapping between sensory input and higher - level cognitive representations.

Title: Role of thalamic projection in NMDA receptor - induced disruption of cortical slow oscillation and short - term plasticity Author: T. Kiss et al..

(«On decadal to century timescales, climate dynamics — the complex interplay of multiple external forcings (rapid and slow), the spectrum of atmospheric and ocean circulation oscillations, interactions with biosphere — determines variations in climate.»)

Moreover some combination of the basic sawtooth mechanism (sudden thermal disturbance followed slow return to equilibrium) could conceivably operate in parallel with oscillations amplified by resonances shaped by spherical harmonics in the mantle cavity, governed by the speed of sound in the mantle.

Not only has the AMOC slowed down (Cunningham et al [2013]-RRB-, but sea surface temperatures in North Atlantic subpolar gyre have begun falling, as have sea surface temperatures in the North Pacific subtropical gyre - best illustrated by the Pacific Decadal Oscillation (PDO) being strongly positive this year.

A new article co-authored by the other of us (Michael Mann), shows that natural ocean oscillations have recently acted to temporarily slow the warming of the Earth's surface temperatures, in combination with a relatively quiet sun, and active volcanoes.

With the recent decline in solar flux and the shift to cool phases of ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.

And with much of the past decade being in the cold phase of the Pacific Decadal Oscillation, there certainly is no surprise to a briefly slower upward climb.

On decadal to century timescales, climate dynamics — the complex interplay of multiple external forcings (rapid and slow), the spectrum of atmospheric and ocean circulation oscillations, interactions with biosphere — determines variations in climate.

These difficulty oscillations are making block creation times very slow on the Bitcoin Cash network and are also resulting in a growing backlog of transactions in Bitcon as well.
