Interesting Facts About Human Brain.
The human brain is a
beautiful thing. It is responsible for all of the technological achievements
that we have reached thus far. And the best part is, our brains are continually
getting smarter. But to develop a better understanding of the brain, as well as
a new found respect, let’s cover the top 10 facts about the brain that you
probably didn’t know about.
1 – The human
brain is the only organ in the human body that lacks nerves despite the fact
that it acts as the central command for the central nervous system. This simply
implies that, the human brain feels no pain.
2 – The human
brain consumes the largest portion of the total energy that is generated in the
human body. To be precise, the brain consumes 20% of that energy despite the
fact that it only represents only 2% of the total body weight. The energy is
vital for maintaining healthy brain cells and fueling nerve impulses.
3 – The
number of neurons present in the brain is approximately 100 billion which is
about 15 times of the total human population on earth. This high number of
neurons increases the processing ability of the brain.
4 – The human
brain is regarded as the fattest organ in the human body. About 60% of the
human brain is comprised of fat which is the highest concentration of fat that
is present in a single organ in a healthy human being. Furthermore, 75% of the
total brain mass is comprised of water which regulates various functions in the
brain.
5 – The
neocortex is the portion of the human brain that is responsible for language
and consciousness. It makes up approximately 76% of the human brain and making
it the largest when compared to that in other animals.
6 – It is
believed by many that, human beings use less than 10% of their brain. This is a
misconception because each and every part of the brain has a known function.
7 – During
early pregnancy, neurons have shown to multiply at a rate of 250,000 neurons
per minute
8 – About
15-20% (750ml) of the total cardiac output is directed to the brain every
minute
.
9 – The
energy consumed by the brain which is approximately 25 watts is sufficient
enough to illuminate a light bulb.
10 – The human
brain is not as perfect as it is thought of since in many instances it has been
found to fool human beings making them to perceive things differently from the
reality.
