The human brain is more complex than any other known structure in the universe. Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.
Here are some Interesting Facts About The Human Brain
1. About 75 percent of the brain is made up of water. This means that dehydration, even in small amounts, can have a negative effect on the brain functions.
2. Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light bulb.
3. When you find yourself sleeping in a new environment for the first time, the brain processes danger and remains half-awake in order to be more aware.
4. In early pregnancy, the neurons develop at an alarming rate of 250,000 per minute.
5. An adult brain weighs about 3 pounds.
6. Exercise slows our brains’ cognitive decline and increased physical activity over the norm can slow our brain’s aging by 10 years.
7. Alcohol doesn’t make you forget anything. When you get blackout drunk, the brain temporarily loses the ability to create memories.

13. A brain freeze is really sphenopalatine ganglion neuralgia. It happens when something you eat or drink something that’s cold.

These constrict when they’re cold and open back up with they’re warm again, causing the pain in your forehead.
14. Babies’ brains grow rapidly. A 2-year-old baby will have an 80% fully grown brain. This rapid development is why paying close attention to your child’s development in the early years is so impactful to their ability as an adult.
15. When the mind recalls a memory, it’s not the original memory. In fact, the act of remembering is an act of creative re-imagination. The put-together memory doesn’t just have a few holes; it also has some entirely new bits pasted in.
