Fun facts about brain

The Brain
The human brain is the most complex and least understood part of the human anatomy. There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered.

1. Have you ever wondered why you react so quickly to things around you or why a stubbed toe hurts immediately? It’s because nerve impulses from your brain to your body move as fast as a high-powered luxury sports car.
2. Your brain operates on the same amount of power as a 10-watt light bulb. That cartoon image of a light bulb over your head when you have a great thought? It’s not far off. Even when you’re sleeping, your brain generates as much energy as a small light bulb.
3. A human brain cell can hold up to five times as much information as the Encyclopedia Britannica. Scientists estimate its storage capacity to be between 3 and 1,000 terabytes, making it more impressive than the National Archives of Britain.
4. Despite making up only 2% of our body mass, the brain consumes 20% of the oxygen that enters our bloodstream. This high oxygen demand makes the brain highly susceptible to damage from oxygen deprivation, so remember to take deep breaths to keep your brain happy and oxygenated.
5. Contrary to what you might think, the brain is more active at night than during the day. While we’re asleep, our brains are hard at work, though scientists are still unsure why. So, thank your brain for those pleasant dreams.
6. It’s said that individuals with higher IQs tend to dream more. However, not remembering your dreams doesn’t mean you lack intelligence, as most of us don’t recall many of our dreams, which typically last only 2-3 seconds.
7. Neurons continue to grow throughout our lives, contrary to earlier beliefs. While they don’t regenerate like other tissues, this ongoing growth adds a new dimension to brain study and understanding illnesses that affect it.
8. Information travels at varying speeds within different types of neurons, with some transmitting as slowly as 0.5 meters/sec and others as quickly as 120 meters/sec.
9. While the brain may be the center of pain perception, it itself cannot feel pain, lacking pain receptors. However, the surrounding tissues, nerves, and blood vessels can cause headaches and other painful sensations.
10. The brain is composed of 80% water, giving it a squishy, jelly-like texture. So, to keep your brain hydrated and functioning optimally, remember to stay hydrated yourself.
