    Posted on 2021-05-13

    The human brain is the central organ of the human nervous system, and the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brain stem, and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs and making decisions as to the instructions sent to the rest of the body. The brain is contained in, and protected by, the skull bones of the head. You may not know the most amazing facts about our brain.22 Facts about Human Brain

    • Your brain generates about 12-25 watts of electricity. This is enough to power a low wattage LED light bulb.
    • It weighs about 3.3 lbs. (1.5 kilograms).
    • The brain makes up about 2 percent of a human's body weight.
    • 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.
    • Computer or video games may help improve cognitive abilities. However, more studies must be conducted to learn how much they help or what types of games help.
    • Your brain uses 20 percent of the oxygen and blood in your body.
    • The human brain will grow three times its size in the first year of life. It continues to grow until you’re about 18 years old.
    • There is 2,500,000 gigabytes of storage space in your brain.
    • After 30 years, our brain gradually begins to lose mass. This may partially explain the reason behind our memory failing us, over time.
