Interesting facts about brain


brain facts,Interesting facts about brain

The human brain is the most complex organ of the human body. There are more than 86 billion neurons in your brain. And thousands of connections are being made between them, due to which you can think this time.

Every human has a different brain from each other, But there are some things which are common in every human being. Your brain works in mysterious as well as interesting ways. The human brain contains everything we know. With all our brain does and remembers for us, have you ever considered how much you know about your brain? Let's explore unknown facts about the brain.

1. Out of sync.

Out of sync is one of the biggest mysteries of our brain. The researcher says that those who have good handwriting are of the average mind and those who have more brains have worse handwriting because their brain works faster than their hands. In other words, their brain is out of sync. Science is still unable to find out Why Brain cannot sync with the body in some people.

2. Dreams

The dreams are still a mystery for Medical Science. Dreams are the stories and scenes that we experience when we are asleep. Studies have found that dreams are also important for our survival. Many people believe that they do not have dreams but the fact is, maximum people, forget 90% of our dreams as soon as they wake up.

And if you observe, you will realize how real dreams seem for a few moments, that seems that dream is the real world for us. Scientists have so far learned that our dreams are related to our real world, even those who are blind from birth have dreams related to touch sensation rather than visualization.

3. Memories

Memories are stored in the brain. You may feel it very simple but believe it is quite complicated. There is no particular place in the mind that there is a store in the memory. Our memory comes from different parts of the brain.

For example, when you are driving, the memory to drive comes from one part of the brain and the meaning of the traffic signal comes from the other part of the brain.

Our brain stores memory in a very advanced manner whenever we do something. When we remember it again, we remember with so much detail. This happens because when we remember something again, then the same Neuron fire that happened in our nervous system at the time of the actual incident.

4. The brain changes Physically.

The first scientists believed that the brain stops changing after an age. But after advanced study, it was discovered that our brain keeps changing its structure along with experience, this is called structural plasticity.

Negative thinking causes most parts of the brain to shrink and many parts of people who are positive remain more active. Do you know that now every part of your brain is resting, even then your brain remains active even if you are in deep sleep, your subconscious still minds Remain active.

5. Phantom limbs

Phantom limb is a very different and interesting imagination of the brain. People with their feet cut off due to an accident or those like this since childhood are still able to feel that their limbs. Scientists are still unable to understand why the brain makes us feel things that do not exist.

6. Weight of the Human Brain

The average weight of a human brain is 3 pounds or 1.35 kilograms, or about 1% to 3% of your body weight, making it the second heaviest of your internal organs, only getting beaten out by the liver. 60% of that is fat in the brain used for making it also the organ with the highest concentration of fat, found in a healthy human body.

In recent years, it has gone to show that fatty acids are among some of the most important molecules that determine your brain's ability to perform. The fats of your brain also create all of the cell membranes in your body; these "good fats" are known as lipids, and our bodies don't manufacture these fats, they come from the foods we eat.

7. Brain produces electricity

Each nerve cell inside your brain has the ability to produce charges Which move across the cell membranes, leading to the manufacture of a small however necessary voltage. This brain fact gave me a shock.

With the typical neuron containing a resting voltage of roughly 70 milli-volts, or .07 volts. Surely this number seems small, but consider the average human brain contains roughly 80 to 100 billion neurons; meaning, your brain generates roughly 12 to 25 total watts of electricity, enough to power and run a dim light bulb. The main source for all that energy is Glucose.

8. How much Power Brain Use?

We have all heard about how humans can only use 5 to 10% of our brain right. I mean, just think of what we could do if we could use more of it. It also turns out that most of the brain is active most of the time, and evidence goes even further to suggest that at any given moment, up to 16% of our brain cells are active.

Although true, that any given moment all of the brain regions aren't firing off concurrently, research derived from imaging technology shows that, like the muscles of your body, there is continuous activity throughout a 24-hour period, even during sleep; sections such as the frontal cerebral cortex and somatosensory areas are usually always active.

9. How much Oxygen Brain Use?

Even though your brain is roughly 2% of your total body weight, it consumes close to 20% of your total energy and oxygen that flows through your body; making it the largest single organ usage of your energy. This energy is used for basic functions such as yawning and more technical uses like fueling electrical impulses.

Research suggests that 2/3 of the brain's energy is used for helping your neurons and nerve cells to fire signals, the remaining 1/3 is believed for cell-health and maintenance, referred to as "housekeeping power".

10. The brain does not feel pain.

The brain does not feel pain, in fact, the brain does not have receptors to feel pain. We feel pain because of a receptor called nociceptors. During surgeries, we are given an injection to inactive nociceptors.

Nociceptors connect the brain and spinal cord, but these nociceptors are not in the brain, so the brain does not feel pain.
