How Much We Use Brain?

Basis, have brains just 1 ounce! Such nagging sometimes asked someone who annoyed face stupidity of others. In fact, according to the results of research conducted at Virginia Commonwealth University; as quoted by the journal Intelligence, brain size has nothing to do with intelligence. And probably no one really has an ounce of brains. Normal human brain size in the range 1.15 to 1.42 kg, roughly the size of an orange (grapefruit).

Large brain is generally owned by people in the Antarctic region as required to support visual function. Understandably, in the northern hemisphere end of a visit there just a little sun, so the weather tends to dim. That's why they need more visibility than we are at the equator, so I could look around.

While the inhabitants of Micronesia region have relatively smaller brains, but certainly not up to 1 ounce. Women have smaller brains than men, 11-12 percent, but that does not mean men are more intelligent.

"Only the brains of different buildings. Areas of the brain associated with intelligence in men with different areas of the brain associated with intelligence in women. There are at least two different brain architectures that lead to the same level of intelligence between men and women," said Prof.. Richard Haier, a consultant neuroscience at the University of California, Irvine.

Need Lots of Energy

Another misperception that had circulated for decades is the opinion that most of us just use your brain about 10 percent. Another major part remains idle assumption was later disputed by some experts, among others, by Barry Gordon, a neurologist from Johns Hopkins School of Medicine, in Baltimore, USA.

"The evidence shows, all day we use the brains of 100 percent," added John Henley, brain specialists from the Mayo Clinic, Rochester, Minnesota, USA.

In fact, when we sleep, he explained, frontal cortex areas that control high-level thinking and self-awareness, or somato sensory area which helps us to feel around, stay active.

He stated that at one time is no more than 10 percent of the brain that we use, but every day all parts of our brain functioned. So no one was allowed to remain unemployed.

Reminded that every part of the brain have their respective functions, such as the frontal lobe related to motor, memory, cognition, and language, then in charge of studying the cerebral cortex of new information, make decisions, etc..

If every time we use every part of the brain simultaneously, it will require a lot of body energy. Most of our body's energy, about 20 percent, is allocated for normal brain function. That means we will lack the energy to walk, breathe, eat, digest food, and other vital activities.

Thousand Tera

Physically, our brain is a soft organ, mostly composed of water (78 percent), fat (10 percent), and protein (8 percent). Beyond the physical aspects, in fact many scientists are only able to uncover a bit of mystery that surrounds the brain. Up to now not clearly known about the dreams, the link between the conscious and the subconscious, the relationship between brain and mind, soul and brain, and many other things, including how much brain capacity.

In this era of computing our brain is often compared with the "brain" that in fact the computer was a human creation. In our brains there are about 100 billion nerve cells (neurons). Between nerve cells that have a connection. Experts suspect, in many connections that the data (memory) is stored. It is estimated that our brain's capacity to store terabytes of data between 1000-1000.

Whatever the size of our brains, most importantly we love him by giving him a healthy diet, exercise regularly, use it only for the positive and beneficial for others, also mengistirahatkannya when tired. Like muscles, the brain can also be achieved and the need to relax, especially if the need to concentrate on the same task in the long term.

To reinvigorate a tired brain, Dr.. Marc Berman suggested for a moment the streets in a city park between the trees big or small, looking at the beautiful green garden, instead of going to a busy shopping center.

"Enjoying the natural beauty of memory will improve performance by up to 20 percent. Instead, go to crowded places instead will add to the anxiety," said researchers from the Rotman Research Institute in Toronto, Canada.

Well, if the brain is cloudy, a fresh look natural, so fresh anymore and can work effectively and productively. (GHS / E.Saptorini)
