Some of these have a longer lead time relative to economic activity than others, so the firm publishes both a longer leading index, which signals changes in activity about a year in advance, and a shorter leading index, which looks six months ahead.
Second-to-second changes in its activity might, though, be expected to be correlated with changes in the amygdalas, because of its role in regulating them. fMRI allows such correlations to be measured.
The indicators are designed to provide early signals of turning points between the expansion and slowdown of economic activity, and are based on a wide variety of data series that have a history of signaling changes in economic activity.
It claims there have been "no major changes" in activity levels in the past five years.
Picard also claims that Madoff records show April Freilich, Picower's longtime assistant, requesting changes in trading activity to generate additional gains.
Decadal and longer changes in sunspot activity impacting warming and cooling cloud cover patterns are now being recognized as an important factor.
They looked at all kinds of factors that can affect our weight such as TV watching, changes in physical activity levels, smoking and the consumption of all kinds of food and drink.
Other that it is all natural caused by changes in solar activity, the angle of the axis of the earth, something, anything, and now cosmic rays and the formation of Aitken nuclei.
FORBES: "Climategate" Scientists Cleared of Wrongdoing - Again
Scientists have been puzzling for some time over exactly what combination of factors is preventing the earth getting even warmer - maybe changes in solar activity, ocean currents or emissions of aerosol pollution.
This shield does not stop all the cosmic rays from getting though, and its effectiveness varies with the long-term changes in the activity of the Sun, which can rise and fall on a timescale of centuries.
They charted changes in the genetic activity in two groups of ageing mice, one group on a standard diet and the other whose diets have been cut to 76% of the standard diet.
Researchers say the reason for the surge is partly because Americans are getting older and fatter, and possibly because of the country's decline in physical activity and some undefined changes in the American diet such as an increase in fat consumption.
But weather does respond to changes in the solar radiation activity of the sun.
Commercial trials are under way on Affectiva's skin-conductance sensors, wristwatch-size devices that detect emotional engagement by measuring tiny changes in sweat-gland activity.
The EPOC detects and processes real time brain activity patterns (small voltage changes in the brain caused by the firing of neurons) using a device that measures electric activity in the brain.
For example, changes in the Sun's activity can send huge amounts of energy towards the Earth which buffet and reconfigure the magnetosphere, causing disruption to communications, power-line failures and even the destruction of satellites.

These match climate models' predictions of what happens when warming is induced by greenhouse gases better than it matches predictions of the result of changes in the sun's activity, the main alternative hypothesis for what might be causing the climate to change.
The patients receiving telephone intervention were called by trained nurses, who asked about the patient's symptoms, medications, and changes in weight, diet and physical activity.
The research indicated that influences in solar changes and intermittent volcanic activity have accounted for at least 80% of observed climate variation over the past half century.
FORBES: Climate Forecasting Models Aren't Pretty, And They Aren't Smart
The virtual world participants reported positive changes in all the healthy eating and physical activity measures except the number of hours slept.
FORBES: Can Second Life Help You Lose Weight And Keep It Off?
Gradually, you should be able to increase your activity and adjust to the changes in your body.
And while LBO transactions aren't threatened by tax changes, those who engage in this kind of activity face the threat of tax increases when it comes to "carried interest" that would reduce the incentives for those in this space to transact at all.
Climate scientists have already looked at changes related to Sun spot activity - a cycle of approximately 11 years - and long-term changes in the Sun's brightness, which has a cycle that lasts for centuries.
These trained police and prosecutors do understand why it is so hard to report, why the testimony sometimes changes and how the fact of participating in the sexual activity doesn't signify enjoyment or lack of harm.
Even for owners who cannot keep a constant eye on their pets, by monitoring and recording the number of steps they take, as well as signs of shivering and external temperature information, the new device enables owners to stay informed about the dog's regular activity levels, making it easy to detect any changes in their pet's health.
ENGADGET: Fujitsu collar monitor proves that all dogs go to the cloud
Past changes in regulatory capital or capital standards have had little significant effect on merger activity.
Changes in food supply and eating habits, combined with a dramatic fall in physical activity, have made obesity a global epidemic.
One new technique being used by some neuroeconomists is transcranial magnetic stimulation, in which a coil held next to the head issues a low-level magnetic pulse that temporarily disrupts activity in a certain part of the brain, to see if that changes the subject's preferences for example, for a particular food and how much he is willing to pay for it.
Part of this light is reflected back, and the pattern of reflection indicates activity in the tissue it has been reflected from in particular, changes in the flow of blood to that tissue.
It is also backed up by work done on both people and laboratory animals, which shows that stress changes the activity of neurotransmitters, the chemicals that carry signals from one nerve cell to another in the brain.
