Amazing Facts About Your Brain
Amazing Facts About Your Brain
If you need to brush up on your knowledge of the human brain - or if you just have a LOVE of learning - look no further, because we've gathered up a list of some of the best brain facts on the planet. Amongst other things, you'll learn why babies' heads are so darned big, why a healthy lunch is good for your body and your brain, why happy thoughts will keep the doctor away and why your lover's cologne makes your heart skip a beat. Check out the list, and if you've got more cool and interesting facts to add, please. Our brain is amazing. All scientific and technological achievements of human civilization come from the brain.
4 to 6 = the number of minutes your brain can survive without oxygen before it starts to die
8 to 10 = the number of seconds you have before losing consciousness due to blood loss
10 to 23 = the number of watts of power your grain generates when you're awake (that's enough to turn on a light bulb!)
20 = the percentages of oxygen and blood flow going to the brain
100,000 = the number of miles of blood vessels in your brain
1,000 to 10,000 = the number of synapses for each neuron in your brain
100 billion = the number of neurons in your brain
Baby Brains
Each person has about the same number of brain cells at birth as in adulthood, but those cells grow, reaching maximum size at about age six.
A newborn's brain triples its size in the first year of life (no wonder BABIES have such big heads!). The sense of touch is the first sense to develop in a fetus, with the lips and cheeks experiencing this sensation at eight weeks.
Keep exercising your brain, because mental activity stimulates the creation of new neurons throughout your whole life.
The Memory Game
New connections are created each and every time you remember something or have a new thought. Stronger, more intense emotional connections are linked to memories prompted by scent.
Memories triggered by scent (like cologne) have a stronger emotional connection, and therefore appear more intense than other memory triggers.
Cherish your sleep because that's probably the best time for your brain to file away all the memories of the day.
Things that Make You Go "Hmmm."
It's not your brain that's hurting when you get a headache - without pain receptors, your brain can't feel any pain.
Your brain knows when you tickle yourself, which is why you don't bend over laughing.
Supertasters have a super power that enables them to sometimes taste flavours that others can't detect; they have more taste buds and a brain that's more sensitive to tastes of foods and drinks. When you sleep, you're virtually paralyzed because your brain creates a hormone to prevent you from acting out your dreams.
About 12% of people dream in black and white.
It's not true that humans only use 10% of their brains; each part of the brain has a purpose.
Your brain is the most energy-consuming part of your body. he brain represents only 2% of the body weight, but it uses up to 20 percent of the body's energy production. he energy is used for cell-health maintenance and to fuel electrical impulses that neurons employ to communicate with one another.
The neocortex (a section of the brain involved with language and consciousness) accounts for about 76% of the mass of the human brain. Human neocortex is much larger than any animals. It gives humans unique mental capacities although its brain architecture is similar to that of more primitive species.
Humans do not use only 10% or less of their brain. This is a common misconception. Even though many mysteries of brain function persist, every part of the brain has a known function.
Neurons multiply at a rate 250,000 neurons per minute during early pregnancy.
About 750ml of blood pumps through your brain every minute which is 15-20% of blood flow from the heart.
The human brain is about 75% water.
Your brain consumes 25 watts of power while you're awake. This amount of energy is enough to illuminate a lightbulb.
It is estimated that the human brain has a raw computational power between 1013 and 1016 operations per second. it's better than any known computer.
Our brain often fools us. It often perceives things differently from the reality. For instance, check the following picture. Square A and B are actually the same shade of gray.
That being said, your brain is the most fatty organ in your body!
