Human Brain Facts
The human brain is one of the most mysterious things in the world. Scientists are spending a lot of time unleashing the truth behind the working of human brains. Soon, human brains will get smart updates, with Elon Musk’s Neuralink.
The human brain is the central organ of the human nervous system, and the spinal cord makes up the central nervous system.
- 60% of the human brain is made of fat.
- Human brain isn’t fully formed until the age of 25.
- Brain’s storage capacity is virtually unlimited.
- Brain size doesn’t decide the smartness. The smaller or bigger, it doesn’t matter.
- Whenever you try to recall something, new connection is established with a brain, just like MySQL.
- Brain information transfer speed is up to 268 miles per hour.
- The human brain can generate about 23 watts of power.
- Spinal cord stops growing at the age of 4. It is the central junction which facilitates communication between the body and brain.
- Some people say human use only 10% of their brains which is just a thought and not a true measure.
- The heaviest normal human brain weighed 4.43 pounds. The human brain weighs 3 pounds and has a texture like firm jelly.
- A small piece of a brain tissue contains 1,00,000 neurons and 1 billion synapses.
- When the mind recalls a memory, it’s not the original memory. In fact, the act of remembering is an act of creative re-imagination. The put-together memory doesn’t just have a few holes; it also has some entirely new bits pasted in.

- There are 100 billion neurons in the brain.
- If the blood vessels in the brain were stretched out, it would cover the length of 100,000 miles.
- On every heart beat the brain gets 20-25% of the blood supplied through arteries.
- Plastination technique is used to preserve the brain sections or other human body parts. It is a unique technique for preservation of biological specimens (dead body) for research & teaching purposes. It was invented by Gunther Von Hagens in 1977 in Germany.
- The brain itself does not feel pain because there are no nociceptors located in brain tissue itself. This feature explains why neurosurgeons can operate on brain tissue without causing a patient discomfort, and, in some cases, can even perform surgery while the patient is awake.

- The parts of the brain that control ‘task-unrelated thought’ (such as daydreaming) are almost always active when the brain is at rest.
- Our brain doesn’t multitask. Multitasking is actually impossible. When we think we’re multitasking, we’re actually context-switching.
- Naps improve brain performance. German researchers have published a study claiming that quick naps can help the brain process and retain information. Not that you need an excuse to fall asleep at your desk every afternoon.
Research indicates that when memory is first recorded in the brain—in the hippocampus, to be specific—it’s still “fragile” and easily forgotten, especially if the brain is asked to memorize more things. Napping, it seems, pushes memories to the neocortex, the brain’s “more permanent storage,” preventing them from being “overwritten.”
