- The human brain weighs about 3 pounds, which is approximately 2% of the body’s total weight.
- Despite its size, the brain uses about 20% of the body’s total energy and oxygen intake.
- The brain consists of about 86 billion neurons or nerve cells.
- It is also made up of about the same number of other types of cells, called glial cells, which provide support and protection for neurons.
- The brain continues to develop until a person is in their mid-20s.
- The human brain is the most energy-consuming organ, using up to 20% of the body’s calories.
- It is the most complex organ in the human body and arguably the most complex structure in the universe.
- Information in the brain travels at different speeds, but it can go as fast as 268 miles per hour.
- The brain’s storage capacity is considered virtually unlimited. It doesn’t get “used up” like computer storage.
- Despite popular belief, we use all of our brains, not just 10%.
- The brain generates about 12-25 watts of electricity. This is enough to power a low-wattage LED light.
- While awake, a human brain can generate enough energy to power a small light bulb.
- Every time you recall a memory or have a new thought, you create a new connection in your brain.
- Regular physical exercise is beneficial not just for the body, but also for the brain. It can enhance cognitive functions and slow down the mental aging process.

- The brain is about 75% water and is the fattiest organ in the body, consisting of a minimum of 60% fat.
- Our brains have a texture similar to tofu – they are squishy and soft.
- Laughing at a joke is no simple task as it requires activity in five different areas of the brain.
- Dreams are believed to be a combination of imagination, physiological factors, and neurological factors. They represent a state of the brain that is both active and perceptually isolated from the environment.
- Brain information travels up to an impressive 268 miles per hour. This is faster than Formula 1 race cars which top out at 240 mph.
