Complex and poorly understood, the brain is what makes everything work properly. The body may be kept alive, but without the brain, a person can’t truly live. Here are some interesting and weird facts about the brain.
- The brain doesn’t feel pain: Even though the brain processes pain signals, the brain itself does not actually feel pain.
- Your brain has huge oxygen needs: Your brain requires 20 percent of the oxygen and calories your body needs — even though your brain only makes up two percent of your total body weight.
- 80% of the brain is water: Instead of being relatively solid, your brain is 80% water. This means that it is important that you remain properly hydrated for the sake of your mind.
- Your brain comes out to play at night: You’d think that your brain is more active during the day, when the rest of your body is. But it’s not. Your brain is more active when you sleep.
- Your brain operates on 10 watts of power: It’s true: The amazing computational power of your brain only requires about 10 watts of power to operate.
- A higher I.Q. equals more dreams: The smarter you are, the more you dream. A high I.Q. can also fight mental illness. Some people even believe they are smarter in their dreams than when they are awake.
- The brain changes shapes during puberty: Your teenage years do more than just change how you feel; the very structure of your brain changes during the teen years, and it even affects impulsive, risky behavior.
- Your brain can store everything: Technically, your brain has the capacity to store everything you experience, see, read or hear. However, the real issue is recall — whether you can access that information.
Information in your brain travels at different speeds: The neurons in your brain are built differently, and information travels along them at different speeds. This is why sometimes you can recall information instantly, and sometimes it takes a little longer.
