The brain is one of the most mysterious organs in the human body. Here are some interesting facts from the paper help review service that will help you learn more about it.

Facts About Brain

1. The brain doesn’t feel pain.

Have you ever wondered how neurosurgeons perform brain surgery without anesthesia? There are simply no pain receptors in the brain. But there are in the cerebral membranes and blood vessels. So when we experience a headache, it’s not the brain that hurts, but the surrounding tissues.

2. The brain works more actively when we sleep.

As the brain works, it creates electrical fields that can be measured on the scalp’s surface using electroencephalography (EEG). The brain is off during sleep, but it is even more active than during the day. While awake, it produces alpha and beta waves and theta waves during sleep, especially in its initial stages. Their amplitude is greater than that of the other waves.

3. Brain cells are not just neurons

There are about ten glial cells per neuron. They provide neurons with access to nutrients and oxygen, separate neurons from each other, and participate in metabolic processes and the transmission of nerve impulses.

4. Falling in love can be seen in fMRI scans

Some people think falling in love is just a concept, but fMRI brain scans prove otherwise. In people in this state, areas of the brain associated with pleasure are active. The scans show “lighting up” places that contain dopamine, a neurotransmitter that causes pleasurable feelings.

5. The brain produces enough electricity to make a small light bulb light up

According to scientists at Stanford University, a robot with a processor comparable in intelligence to the human brain would need at least 10 megawatts of electricity to function correctly. And our neurons produce enough energy during the day to light an electric light bulb. In addition, the brain works much faster than the most intelligent computers.

6. The brain is 60% fat

The brain is the organ that contains the most fat. That’s why a diet rich in healthy fats (omega-3 and omega-6) is necessary for health. They strengthen brain cell walls and carry and store fat-soluble vitamins. In addition, fats reduce inflammation and help the immune system work properly.

7. Nerve cells need oxygen and glucose to survive

These two substances are necessary for the functioning and survival of the human brain. It suffers irreversible damage if it does not get enough oxygen or glucose for 3-5 minutes. Curiously, death is rarely instantaneous. Even if a person is decapitated, the brain does not die for another few minutes as long as there is oxygen and glucose in the cells.

8. The memory capacity of the brain is almost unlimited

You can’t know too much or have so much new information that there’s nowhere else to put it (although that’s what it seems like after long meetings). Our brains, unlike computers and phones, never run out of space. Although for example, lack of sleep can hurt our ability to remember data

9. The brain, like muscles, is subject to the “Use it or lose it” rule

We can expand our cognitive reserve, or the brain’s innate ability to recover, through learning and new experiences. People with more developed mental resources have been shown to cope better with the unexpected. But if the brain is not used, this reserve will shrink.

10. Short-term memory lasts 20-30 seconds

Have you ever wondered why we forget what we meant to say after we are distracted for a short time? It concerns the brain’s ability to retain small amounts of information in memory. It stores it for quick access, only 20-30 seconds. Numbers, for example, are held in memory for an average of 7.3 seconds, and letters for 9.3 seconds.
