Human Brain Facts
The human brain is the main organ of the human central nervous system, hence the need to know the human brain facts. It is located in the head, protected by the skull. It has the same general structure as the brains of other mammals, but with a more developed cerebral cortex. Scientists and doctors have devoted tremendous time of their lives to learning how the brain works.
The field of neuroscience is still in its embryonic stage, the human brain has amazing facts which has be a surprise to all ages.
Below are 50 wonderful brain facts including how it works, how it develops, what it controls, how it affects sleep, dreams, and memory, and more, which may be helpful.
- Water. The brain is made up of about 75% water.
- weight. The typical brain is about 2% of a body’s weight but uses 20% of its total energy and oxygen intake.
- Neurons. Your brain consists of about 100 billion neurons. Each neuron connects with, on average, 40,000 synapses.
- Blood vessels. There are 100,000 miles of blood vessels in the brain.
- Brain Cells: All brain cells are not alike. There are as many as 10,000 specific types of neurons in the brain.
- Neurons. Neurons develop at the rate of 250,000 neurons per minute during early pregnancy.
- Brain Damage: Only 5 minutes without oxygen can cause brain damage.
- Newborn’s growth. A newborn baby’s brain grows about three times its size in the first year. The REAL Reason Your Skin is Aging [Shocking Video]
- Brain Speed: Brain information moves anywhere between 1 mph and an impressive 268 miles per hour. This is faster than Formula 1 race cars which top out at 240 mph.
- Cerebral cortex. The cerebral cortex grows thicker as you learn to use it.
- Brain Size: Men’s brains are 10% bigger than women’s, even after taking into account larger body size.
- New neurons. Humans continue to make new neurons throughout life in response to mental activity.
- First sense. The first sense to develop inside the utero is the sense of touch. The lips and cheeks can experience touch at about 8 weeks and the rest of the body around 12 weeks.
- Brain IQ: We are not getting smarter. Since the Victorian era, average IQs have gone down 1.6 points per decade for a total of 13.35 points.
- Oxygen. Your brain uses 20% of the total oxygen in your body.
- Blood. As with oxygen, your brain uses 20% of the blood circulating in your body.
- Unconsciousness. If your brain loses blood for 8 to 10 seconds, you will lose consciousness.

18. Brain Multitasking: Multitasking makes you less productive. When you multitask, your brain simply rapidly toggles back and forth between tasks. This results in decreases in attention span, learning, performance, and short-term memory.
19. Wattage. While awake, your brain generates between 10 and 23 watts of power–or enough energy to power a light bulb.
20.Brain & Computer: The brain is better at interpreting the outside world and coming up with new ideas than the computer. The brain is capable of imagination
21.Brain cells cannibalize: Brain cells cannibalize themselves as a last ditch source of energy to ward off starvation. So in very real ways dieting can force your brain to eat itself.
22.Brain death. The brain can live for 4 to 6 minutes without oxygen, and then it begins to die. No oxygen for 5 to 10 minutes will result in permanent brain damage.
24. Highest temperature. The highest human body temperature ever recorded was 115.7 degrees–and the man survived.
26. Love hormones and autism. Oxytocin, one of the hormones responsible for triggering feelings of love in the brain, has shown some benefits to helping control repetitive behaviors in those with autism.
27. Brain cells damage by alcohol: In spite of what you’ve been told, alcohol doesn’t kill brain cells. It “only” damages the connective tissue at the end of neurons.
28. Food and intelligence. A study of one million students in New York showed that students who ate lunches that did not include artificial flavors, preservatives, and dyes did 14% better on IQ tests than students who ate lunches with these additives.
29. Brain & Music Listening to certain kinds of music can improve memory and concentration, there’s nothing unique about listening to Mozart.
30. Seafood. In the March 2003 edition of Discover magazine, a report describes how people in a 7-year study who ate seafood at least one time every week had a 30% lower occurrence of dementia.
31. Brain & Age: It is also part of the brain facts that your brain starts slowing down at the ripe old age of 24 but peaks for different cognitive skills at different ages. In fact at any given age, you’re likely getting better at some things and worse at others.
32. Dream showings. Japanese researchers have successfully developed a technology that can put thoughts on a screen and may soon be able to screen people’s dreams.
34. Imaginary playmates. A study from Australia showed that children with imaginary playmates between the ages of 3 and 9 tended to be first-born children.
35. Brain is Soft: The human brain is not solid. It’s soft and squishy similar to the consistency of soft tofu or soft gelatin. And it’s very fragile.
36. Reading faces. You can determine if someone is in a good mood, is feeling sad, or is angry just by reading the face. A small area in the brain called the amygdala is responsible for your ability to read someone else’s face for clues to how they are feeling.
37. Subconscious mind.: Think you’re in control of your life? Think again. 95% of your decisions take place in your subconscious mind.
38. Ringing in the ears. For years, medical professionals believed that tinnitus was due to a function within the mechanics of the ear, but newer evidence shows that it is actually a function of the brain.
39. Second brain: Another amazing brain fact is that the brain in your head isn’t your only brain. There’s a “second brain” in your intestines that contains 100,000 neurons. Gut bacteria are responsible for making over 30 neurotransmitters including the “happy molecule” serotonin.
40. Pain and gender. Scientists have discovered that men and women’s brains react differently to pain, which explains why they may perceive or discuss pain differently.
41. Zombies: Some scientists believe zombies could be real and that it’s possible a mutated virus or parasites could attack our brains and rapidly spread throughout large populations causing essentially a “zombie apocalypse.”
42. Supertasters. There is a class of people known as supertasters who not only have more taste buds on the tongue, but whose brain is more sensitive to the tastes of foods and drinks. In fact, they can detect some flavors that others cannot.
43. Blood-brain barrier: A blood-brain barrier protects your brain from foreign substances. But it doesn’t work perfectly. The nicotine in smoke rushes into the brain in a mere 7 seconds. Alcohol, on the other hand, takes 6 minutes.
44. Sleeping pills : Prescription sleeping pills don’t put you to sleep. They put your brain into a state similar to being in a coma, essentially bypassing any restorative value of sleep.
46. Decision-making. Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.
47.Brain has no pain receptors: Another amazing brain fact is that pain is processed in your brain, your brain has no pain receptors and feels no pain. This explains how brain surgery can be performed while the patient is awake with no pain or discomfort.
48. Brain can be preserve: The story of Albert Einstein’s brain led credence to these brain facts. The pathologist who performed Einstein’s autopsy kept the brain in a jar in his basement for 40 years. Eventually he made a cross-country trip with the brain in a Tupperware container to deliver it to Einstein’s granddaughter. See more in Driving Mr. Albert: A Trip Across America with Einstein’s Brain.
49. Boredom. Boredom is brought on by a lack of change of stimulation, is largely a function of perception, and is connected to the innate curiosity found in humans.
50. Adenosine. Caffeine works to block naturally occurring adenosine in the body, creating alertness. Scientists have recently discovered this connection and learned that doing the opposite–boosting adenosine–can actually help promote more natural sleep patterns and help eliminate insomnia which is also part of the brain facts.
