Here are 20 remarkable Brain facts not known by many people

But how much do we know about our own BRAIN : Image

The brain is the crown gem of the human body. It is the seat of intelligence, interpreter of the senses, initiator of body movement, and controller of behavior. The human brain is the most complex organ of the body, and arguably the most complex thing on earth. But how much do we know about our own BRAIN

How many brain cells are in your brain?

The average adult human brain has about 100 billion cells.  It’s still a mystery exactly how these connections work together to create all the marvels of our brains.

Longest living cells in the body

The longest living cells in the body prize goes to brain cells. Most of our brain cells stay  from birth to death. The wiring of these cells changes constantly through our lives.

Water, Water everywhere

Brain is made up of 73% water. 2% dehydration is enough to affect attention, memory and other cognitive skills

Brain feels no PAIN

Brain  do not have any pain receptors. Hence surgeons can perform brain surgery while you are awake. The pain experienced with headache/migraine is because of  the pain receptors present in  layers of coverings, blood vessels, the scalp and some muscles that surrounds the brain.

Brain Loves Cholesterol

Twenty-five percent of the body’s cholesterol resides within the brain. Without proper supply of cholesterol, brain cells die.

Brain is always THINKING

The brain on an average is believed to generate around 50,000 thoughts per day. Sad part is that, in most people 70% of these thoughts are negative. 

Human brain is not SOLID

The human brain is neither solid, nor liquid. It’s soft and squishy similar to the consistency of soft tofu or soft gelatin. And it’s very fragile.

We have a second brain too

The human brain is the most complex organ of the body, and arguably the most complex thing on earth

The brain in your head is not the only brain. There’s a second brain” that lies in intestines that contains around 100 million neurons

Brain generates enough electricity to power a 25-watt light bulb

A single neuron generates only a tiny amount of electricity, but all of the neurons together can generate enough electricity to power a low-wattage bulb.

Oxygen is a Must

The brain can survive without oxygen only for 4-6 minutes after which it begins to die. Lack of oxygen for 5-10 minutes can lead to permanent brain damage.

Always active

Brain is only about 2% of human body weight, but brain cells use twice as much energy as other cells in body. Brain cells are always active, even during sleep.

Brain is More Active When You Sleep

The brain processes complex stimuli during sleep, and uses this information to make decisions while awake. Researchers at the University of Rochester found that during sleep, the brains clear out damaging molecules associated with neurodegeneration. 

Higher IQ = more dreams

It’s a proven fact that people with high IQ (Intelligence Quotient), dream more. Scientists have discovered, that while everyone dreams, the frequency of dreams is significantly higher in those of above average intelligence.

Left, Right, Left

The right side of brain controls movements on the left side of body and the left side of brain controls movements on the right side. So if stroke affects the left part of brain, right arm or leg would get paralyzed.

Brain grows faster in Girls than Boys

For girls, the brain reaches its largest physical size around 11 years old and for boys, the brain reaches its largest physical size around age 14. But, this difference in age does not mean either boys or girls are smarter than one another

The more you use your brain, the stronger it stays

Learning new skills and doing mental tasks makes the connections between brain cells stronger. Staying curious can help it stay sharp forever.

What raises chances of having a stroke?

Diabetes accompanied with High blood pressure and smoking can damage blood vessels including those that supply your brain, raising the risk for a stroke.

You can’t Tickle yourself

When you try to tickle yourself, the cerebellum predicts the sensation and this prediction is used to cancel the response of other brain areas to the tickle.

Einstein’s Brain

A 1999 study of Einstein’s brain, based on photographs taken of it after he died in 1955, showed that the parietal lobes, which are linked to math ability, appear 15% wider than normal. But the size of his brain was a little smaller than average.

Neurons Multiply a Million time During Pregnancy

At the beginning of pregnancy Fetal neurons multiply at a rate of 250,000 per minute

Now your Brain knows a lot about itself….

  1. I’m going to show my husband the fact that the brain is always thinking – he keeps telling me I’m not giving my brain a break and always bombarding it with thoughts 😀

  2. This is super Informative. I never felt science was boring ever, which many of them say :p till date. Many unknown facts are been mentioned above, thankyou for sharing. One recent incident, I lost my close loved one because of Brain Surgery not done properly 🙁 Thanks for sharing this dear.

  3. I always enjoy reading your posts and this is yet another informative post. You’ve shared many facts which I didn’t know earlier…
