KNOW YOUR BRAIN - Part II

Continued from first post:

There is 25,00,000 gigabytes of storage space in you brain. The top-of-the-line iPhone 7 has 256.

The brain of an adult human weighs around 3 pounds (1.5 kg).

Although it makes up just 2% of the body weight, it used around 20% of its energy.

If you laid out all of the blood vessels in your brain end-to-end, they would stretch half way to the moon (1,20,000 miles)

Reading aloud promote brain development. It is indeed one of the strange facts about the brain because we usually teach our children to read and talk politely. But to promote brain development in your child, you should read and talk aloud in front of them.

The attention spans of human brains are getting shorter. We have lost almost four seconds of our attention span in the past 15 years. This means we cannot concentrate on one thing for more than eight seconds on an average.

Being able to access information quickly (eg. on the internet) makes you less likely to rember it. It is great being able to access almost any piece of information in a few seconds, and resources such as Google, Wikipedia and You Tube have clearly been major parts of a revolution in how we find information. But studies suggest if the brain knows it can just access it again so easily, it is less likely to bother remembering the information itself.

One study looked at students in New York and showed that those who ate lunches that did not include artificial flavours, presevatives, and dyes did 14% better on IQ tests than the students who ate lunches with these additives.

Our brain prefers images over text. Participants in studies only remember about 10%  of information presented orally when they are tested 72 hours after instruction. However, that number jumps by about 65% when an image is added to the learning process.

The human brain is divided into two hemispheres, the left and right,  connected by a bundle of nerve fibres called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. The left brain controls all the muscles on the right hand side of the body; and the right brain controls the left side. One hemisphere may be slightly dominant, as with left or right-handedness.

Our brain usually choose the first option on lists. Studies show when people are presented with a list of options they are most likely to pick whatever is first. The same is shown to hold true for voting.

There are about 100 billion neurons in a human brain, whic is about the same as the number of stars in the Milky Way galaxy.

Feeling tired? Go ahead and yawn. Yawning cools down the brain, research suggests. Sleep deprivation raises brain temperature.
