Short time — huge results

The human brain is the command center for the human nervous system. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than the brains of many other mammals, such as dolphins, whales and elephants.

Did you know that 15 minutes of training every day can make you smarter? Brainable makes games that suit you. Just a short session, easy to fit in anywhere. The human brain is the command center for the human nervous system. It receives signals from the body's sensory organs and outputs information to the muscles. The human brain has the same basic structure as other mammal brains but is larger in relation to body size than the brains of many other mammals, such as dolphins, whales and elephants.

How much does the human brain weight

The human brain weighs about 3 lbs. (1.4 kilograms) and makes up about 2% of a human's body weight. On average, male brains are about 10% larger than female brains, according to Northwestern Medicine in Illinois. The average male has a brain volume of nearly 78 cubic inches (1,274 cubic centimeters), while the average female brain has a volume of 69 cubic inches (1,131 cubic cm). The cerebrum, which is the main part of the brain located in the front area of the skull, makes up 85% of the brain's weight.

How many brain cells does a human save

The human brain contains about 86 billion nerve cells (neurons) — called "gray matter," according to a 2012 study published in the Proceedings of the National Academy of Sciences. The brain also has about the same number of non-neuronal cells, such as the oligodendrocytes that insulate neuronal axons with a myelin sheath. This gives axons (thin strands through which electrical impulses are transmitted between neurons) a white appearance, and so these axons are called the brain's "white matter."

Over cool facts about the brain

  1. The brain can't multitask, according to the Dent Neurologic Institute. Instead, it switches between tasks, which increases errors and makes things take longer.
  2. The human brain triples in size during the first year of life and reaches full maturity at about age 25.
  3. Humans use all of the brain all of the time, not just 10% of it.
  4. The brain is 60% fat, according to Northwestern Medicine.
  5. The human brain can generate 23 watts of electrical power — enough to fuel a small lightbulb.

Conclusion

The human brain weighs about 3 lbs. (1.4 kilograms) and makes up about 2% of a human's body weight. On average, male brains are about 10% larger than female brains, according to Northwestern Medicine in Illinois.
