People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

What happens during the brain's resting state?

Over the past few years, some researchers have been adding a bit of down time to their study protocols, Nature News reports. While subjects are still lying in the functional magnetic resonance imaging (fMRI) scanners, the researchers ask them to try to empty their minds. The aim is to find out what happens when the brain simply idles. And the answer is: quite a lot.

 

Some circuits must remain active; they control automatic functions such as breathing and heart rate. But much of the rest of the brain continues to chug away as the mind naturally wanders through grocery lists, rehashes conversations and just generally daydreams. This activity has been dubbed the resting state. And neuroscientists have seen evidence that the networks it engages look a lot like those that are active during tasks.

 

Resting-state activity is important, if the amount of energy devoted to it is any indication. Blood flow to the brain during rest is typically just 5–10% lower than during task-based experiments. And studying the brain at rest should help to show how the active brain works. Research on resting-state networks is helping to map the brain’s intrinsic connections by showing, for example, which areas of the brain prefer to talk to which other areas, and how those patterns might differ in disease.

Dec19 I believe that avioding prepared foods would be the first step in order to lose weight. They can taste beneficial, but processed foods possess very little vitamins and minerals, making you take more just to have enough vigor to get through the day. In case you are constantly eating these foods, switching to grain and other complex carbohydrates will assist you to have more vigor while feeding on less. Thanks alot : ) for your blog post.
