Sentences with phrase «magnetic activity during»

Cosmogenic isotopes provide the most extendable indirect data on the cosmic ray flux, the state of the heliosphere, and hence on the solar magnetic activity during the past.

Not exact matches

A set of functional magnetic resonance imaging recordings of the temporal lobes during both tasks backed up the researchers» hypothesis: brain activity was similar each time a volunteer consciously looked at the same face or house, but invisible stimuli evoked a more variable response (Science, DOI: 10.1126 / science.1180029).

While measuring brain activity with magnetic resonance imaging during blood pressure trials, UCLA researchers found that men and women had opposite responses in the right front of the insular cortex, a part of the brain integral to the experience of emotions, blood pressure control and self - awareness.

The study, published online July 29 in Cerebral Cortex, used functional magnetic resonance imaging, or fMRI, to examine children's brain activity at rest and during two tasks: solving simple math problems and looking at pictures of different faces.

During solar maximum, when sunspots are numerous and solar activity is at its peak, magnetic lines surround the sun.

To examine the link, researchers measured blood glucose levels and hunger, while also using functional magnetic resonance imaging (MRI) to observe brain activity during the crucial four - hour period after a meal, which influences eating behavior at the next meal.

Sadee contacted Alessandro Bertolino at the University of Bari in Italy, who was doing research that involved monitoring the brain activity of 117 volunteers with functional magnetic resonance imaging (fMRI) during memory tests.

During this test, the subjects were scanned with functional magnetic resonance imaging (fMRI) to measure their brain activity while carrying out the task.

The experiments used functional magnetic resonance imaging to measure increased blood flow throughout the brain, a marker of increased neural activity, during a wide range of activities, including finger - tapping, whistling, chewing, drawing, writing, reading, watching a movie and playing video games and memory games.

During their early life, Sun - like stars spin very fast, creating extremely high levels of magnetic activity that drive powerful stellar flares, coronal mass ejections, and an outpouring of X-ray and ultraviolet radiation.

Other projects launched during Prager's tenure include a new facility to investigate magnetic reconnection, an explosive process that is found throughout the universe; a plasma nanotechnology laboratory, and fledgling activities in mass separation using ideas from plasma physics.

By combining neuronal tracing with behavioral experiments leading to sensory - driven gene expression of the neuronal activity marker ZENK during magnetic compass orientation, we demonstrate a functional neuronal connection between the retinal neurons and Cluster N via the visual thalamus.

There is no room for complacency, Svalgaard warns: «If the Earth does cool during the next sunspot crash and we do nothing, when the sun's magnetic activity returns, global warming will return with a vengeance.»

We find during the past 11,400 years the Sun spent only of the order of 10 % of the time at a similar high level of magnetic activity and almost all of the earlier high - activity periods were shorter than the present episode.»

For a while I thought that direct magnetic inductive heating of the Earth might be associated with the increased warming observed during periods of high solar activity.

Because model A contains some remaining magnetic activity, our approach does not imply that the solar dynamo stops during the periods when the modulation potential is equal to zero.

When the magnetic fields surrounding the earth were strong, during periods of high sunspot activity, cosmic rays were deflected away from the earth.

The advantage of the strong magnetic clasp is that it keeps the tracker steady and safe even during dynamic sporting activities.
