We all know that the brain is an organ of soft nervous tissue contained in the skull. Its function is to coordinate every sensation in our body intellectual and nervous. We learn it as early as elementary days but do you know that there are other facts about the brain that even teacher doesn’t teach in the school.

Here are some facts that brain about the brain you need to know:

1. Brain use 100% of it.

7 Facts About the Brain you Need to Know

Good news folks, we use 100% of our brain at a given time. If you watched the movie “Lucy” a student that surgically implanted with a package containing a powerful chemical, that leaks into her system, that give access to 100% of her brain which give her superhuman abilities. well, I’m sorry to inform you that it is only a myth. The 10% thing statement may have been started with a misquote of Albert Einstein or perhaps it William James who wrote “We are making use of only a small part of our possible mental and physical resources.”

2. Brain shrinks during pregnancy

7 Facts About the Brain you Need to Know

Many women during pregnancy suffer from memory loss or sometimes forgot appointments or even misplace things. The baby might be eating your brain, just kidding. Fear not, there are no hard evidence or a link that changes in size can lead to memory loss nor any cognitive brain function due to pregnancy. Research say that  the number of the cells in the brain doesn’t change but the actual brain cell volume during pregnancy. It shrinks due to being less water in the cell or combined increased nutritional requirement of having to feed both mother and child. Pregnant woman brain-volume increase in six months after delivery.

3. Brain has no pain receptor

7 Facts About the Brain you Need to Know

The brain itself does not feel pain because there are no pain receptors located in the brain tissue itself. Even you poke it with a knife you will feel nothing. That is why surgeons can actually perform brain surgery on a patient while they are still awake. Headaches, however, is a different story. The brain works as a signal impulse that transmit through the nerve into the spinal cord, and eventually all the way to your brain.

4. Brain structure changes

7 Facts About the Brain you Need to Know

The structure of the brain is constantly changing from birth throughout the lifetime. These changes are referred to as brain plasticity, and they are associated with functional changes of the human brain. Researchers believed that the brain possesses the remarkable capacity to reorganize pathways, create new connections and, in some cases, even create new neurons. The brain sends messages along certain pathways of neurons, forming new connections. In fact, the structure of your brain changes every time you learn, as well as whenever you have a new thoughts and memories.

Here are some factors that affect the brain structure:

  • Growth or aging
  • Experience or new knowledge
  • Psychoactive drugs like amphetamine and morphine
  • Hormones – estrogen, testosteron
  • Dietary factors – vitamin and mineral supplements
  • Disease – Parkinson’s disease, schizophrenia, epilepsy, or stroke
  • Stress
  • Brain injury

5. Brain produce enough electricity to light a bulb

7 Facts About the Brain you Need to Know

Believe it or not, the brain has 100 billion cell that releases chemical and electrical signals between neurons along billions of tiny neuron highways. Activities in your brain never stop with countless signals inside every second. Neurons create and send more messages and while a single neuron generates electricity. with all your neurons emitting electric signals can generate enough electricity to power a low-wattage bulb.

6. You can survive with only half a brain

Yes! A very few cases show that people survive with only half of their brain with no significant ill effect. There is a very rare surgical procedure called Hemispherectomy where half of the brain is removed or disabled. This procedure is used to treat a variety of seizure disorders where the source of the epilepsy is localized to a broad area of a single hemisphere of the brain, among other disorders. Strange but true but a recent study found that 86 percent of the 111 children who underwent hemispherectomy are either seizure-free do not require medication. Of course, the operation has its downside but most of the time patient survive with half a brain.

7. Brain transmit speed faster than 150mph

Neurons relay information to your spinal cord and brain at a speed of more than 150 miles per hour. Your brain then uses motor neurons to transmit the message back through your spinal cord to react. You have only seconds to act while your body accessing the signals your brain quickly calculates when, where, and at what speed you will need to react. Motor neurons can relay this information at more than 200 miles  per hour.


Exercising can also help make you smart. When you exercise the blood flows to the brain increase. Your brain also releases hormones that can help you learn more. So, get moving to get smarter. If you know some other facts you can post it below.
