Astonishing facts about the human brain


The human brain is a monster of a computer. It outclasses the best of the best of human built computers as far as memory, capacity and speed is concerned. Unfortunately, it is also the “computer” that is the most underutilized and sometimes misused!

1. Weight of the human brain

The average weight of the human brain grows phenomenal between birth and adulthood. It can reach a final weight of about 1.4kg for men and 1.3 kg for women.

2. Brain size and intelligence

There is no correlation between brain size and intelligence. The brain of a man is usually slightly larger than that of a woman’s. Interesting enough, in both sexes the brain makes up a similar proportion of the total body weight.

3. Brain hemispheres

The human brain is divided into two hemispheres, each a mirror image of the other. The right hemisphere controls the muscles of and receives information from the left half of the body; the left hemisphere monitors and controls the right half of the body.

4. Left-handed vs. right-handed people

In right-handed people the left side of the brain is concerned with such skills as reading, writing and talking. The right hemisphere deals with artistic activity and the mechanisms of the imagination. In left-handed people the functions of the two hemispheres may be reversed.

5.  Feeling of pain

Pain from any injury or illness is always perceived by the brain. However, the brain itself is immune against pain as it contains none of the specialised receptor cells that sense pain in other parts of the body.

Go out and maximize the utilization of the best computer there will ever be!
