Intelli Brain

I was reading thru some biological facts of human brain behaviors and came across some interesting facts, and like to share with you:

Your brain is full of nerve cells, but it has no pain receptors. Doctors can operate on your brain while you’re awake and you won’t feel a thing.

Your brain has about 100 billion neurons. A typical brain cell has from 1,000 to 10,000 connections to other brain cells.

The right side of your brain controls the left side of your body, and the left side of your brain controls the right side of your body.

An analysis of 1 million students in a New York school district showed that school cafeteria food affected IQ scores to an astonishing degree. When preservatives, coloring, dyes and artificial flavors were removed from the cafeteria menu researchers found that 70,000 students performed two or more IQ grade levels higher than before

Intelligent Quotient is not influenced by family size or birth order. There is some confusion on this matter due to the fact that smart families usually have few children. However there is absolutely no evidence to suggest that you will have a low IQ if you belong to a large family. There is also no evidence that the first born child will be more intelligent than the rest.

Certain smells may improve your ability to pass exams. British research indicates students revising for exams could use scent to improve their marks, but also that smells associated with failure can worsen results. The smell of rosemary is also said to enhance mental performance.
