Facts About the Human Brain
Human Brain is the most interesting organ of the body. It is the hub for the
human nervous system. It receives input from organs like sensory organs and
sends output to other part of the body like muscles, for appropriate actions to
be taken. That's not all. Human Brain has some amazing features and
characteristics which will make your jaw-drop. We will discuss more about human
brain but first let's explore this organ's whereabouts to know it better.
consume more energy than other parts or organs of the body. The mind or the
brain is the powerhouse which processes all mental and psychic activities, may
be this is a probable reason why it consume more energy than any other part of
the Body. The brain is only 2% on the total body weight but consumes about 20%
of the energy.
2. Lack of
oxygen in the brain for 5 to 10 minutes will result in permanent brain damage.
After a cardiac or respiratory arrest, resuscitation, suffocation, prolonged
seizure, drowning, choking, or (smoke) poisoning, if there is oxygen
deficiency, then the brain may damage permanently.
Brain Keeps Developing Until your Late 40s. In other words, brain only fully
'matures' in middle age.
time you form a memory, a new brain connection is created inside your brain and
is supported by patterns of neuron activity in the prefrontal cortex. Each
neuron has the capability to connect with 40,000 synapses on an average.
brain mostly consists water. Yes, you read it right! 73% of human brain is
water and 2% of dehydration is enough to affect the memory, attention and other
6. The dry
weight of the brain is around 3 pounds or 1.5 kilograms. You will be amazed to
know that it is the fattiest organ of your body as it contains 60% fat (dry
brain Contains about 100 billion neurons. Neurons also have the capability to
connect more than 10,000 other neurons which implies that it can be a huge
connection. Thee connection of neurons aids you to develop ideas, recall
memories and develop a certain personality trait etc. Human brain is said to
contain roughly 86 billion brain cells. For example, a student learn about Physics Formulas or Geometry Formulas, which
will help him/her to understand the real-life problems throughout their life.
beings are said to the most intelligent animal in the world but it's
astonishing to know that we use merely 10% or more of our brain. Though there
are still other theories which states that this 10% theory is entirely bogus
and human use way, way more than 10% or the brain power.
pregnancy, the neurons in a foetus brain grow at a rate of 250,000 neurons per
minute. Cells and neurons develops for several years after birth. A
2-year-old’s brain is said to of 80% of adult brain’s size. Not only in foetus,
but also a pregnant lady's neurons multiplies at a faster rate. There are no
proper explanations for this but scientists states that this rapid
multiplication of neurons in a pregnant lady, makes learning new things and
remembering old ones is much faster and easier than someone who isn't.
human brain pumps a lot of blood per minute and is capable of pumping more.
Your brain also uses 20% of the total oxygen present in your body.
is vulnerable to a virus which can attack the human DNA and make them dull,
less intelligent, cause harm to the brain activity, memory and learning power.
brain has tremendous capability. When awake, it can produce sufficient
electricity to power a small light bulb. It produces 12-25 watts of
Cholesterol is a vital component for brain. Brain cells continue to live with
the aid of cholesterol. 25% of the human body's cholesterol is present and used
in the brain. Lack of cholesterol can lead to the death of brain cells as well.
are almost 10,000 types of neurons present in the brain. Within which more than
1 lac chemical reactions takes place every second.
average human brain is believed to sow the seeds of near about 50,000 thoughts
each day and scientists estimate that 70% of these thoughts are negative.
of the body size or weight, Men's brain size is 10% bigger than that of Women's.
the ages, the size of the human brains have shrink by the size of a tennis
ball; IQ level has gone down by 1.6 points per decade; and the average
attention span has dropped from 12 seconds to 8 seconds since 2000, but Human
civilization is developing. Thus it would be inappropriate to state whether we
are growing or declining in our development chart.
to conclude with a small yet significant fact for you. Albert Einstein’s brain
weighed 1,230 grams which is near about 10% smaller than the average human
brain weight. But it was his brain's neuron density which was way higher than
the average and this is what mattered in making him such a great and
