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 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.
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.
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….
