50 Mind-Blowing Facts of the Human Brain

The study of the human brain is one of the least explored areas in science. Even experts agree that we don’t know much more about the brain than we currently know. In recent years, our knowledge of the brain has exploded, much of what we know about the brain has been discovered in the past 15 years. So, many facts about the human brain have not yet found a place in the public’s awareness.

Mind-Blowing Facts of the Human Brain

The most complex expression of intelligence we know of resides between our ears. Certainly! Here are 50 mind-blowing facts about the human brain:

3. The brain uses about 20% of the body’s oxygen and energy.

4. The brain can generate approximately 10-23 watts of power, enough to power a light bulb.

5. The brain is made up of about 75% water.

6. The brain contains about 100,000 miles (160,000 kilometers) of blood vessels.

7. The human brain continues to develop and grow until the age of 25.

8. The brain can process information at a speed of about 268 miles per hour (432 kilometers per hour).

9. The human brain can store an estimated 2.5 petabytes (or 2.5 million gigabytes) of information.

10. The brain can produce new neurons throughout a person’s life in a process called neurogenesis.

11. The brain can generate and sustain about 50,000 thoughts per day.

12. It is estimated that the brain can make up to 20 million billion calculations per second.

13. The brain is divided into two hemispheres, with each hemisphere responsible for controlling the opposite side of the body.
