Fun Facts About Our Grey Matter.

The brain is a cool aspect of our human existence and it seems I always am mentioning some of its mystery thought out my blog. So I found some of the most interesting facts about our gray matter on the web.
Results from cognitive tests show 30% of 80-year-olds perform as well as young adults.
• Your brain is about 2% of your total body weight but uses 20% of your body’s energy.
• The energy used by the brain is enough to light a 25 watt bulb.
• More electrical impulses are generated in one day by a single human brain than by all the telephones in the world.
• How much does human brain think? 70,000 is the number of thoughts that it is estimated the human brain produces on an average day.
• After age 30, the brain shrinks a quarter of a percent (0.25%) in mass each year.
• Albert Einsteins brain weighed 1,230 grams (2.71 lbs), significantly less then the human average of 1,300g to 1,400g (3 lbs).
• 89.06 is the percentage of people who report normally writing with their right hand, 10.6% with their left and 0.34% with either hand.
• 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.
• Speed. Information can be processed as slowly as 0.5 meters/sec or as fast as 120 meters/sec (about 268 miles/hr).
• Wattage. While awake, your brain generates between 10 and 23 watts of power–or enough energy to power a light bulb.
• Yawns. It is thought that a yawn works to send more oxygen to the brain, therefore working to cool it down and wake it up.
• Neocortex. The neocortex makes up about 76% of the human brain and is responsible for language and consciousness. The human neocortex is much larger than in animals.

• 10%. The old adage of humans only using 10% of their brain is not true. Every part of the brain has a known function.
• 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.
• Highest temperature. The next time you get a fever, keep in mind that the highest human body temperature ever recorded was 115.7 degrees–and the man survived.
• Stress. Excessive stress has shown to “alter brain cells, brain structure and brain function.”
• 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.

• 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.
• 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.
• Tickles. You can’t tickle yourself because your brain distinguished between unexpected external touch and your own touch.
• Create associations. Memory is formed by associations, so if you want help remembering things, create associations for yourself.
• Scent and memory. Memories triggered by scent have a stronger emotional connection, therefore appear more intense than other memory triggers.
• Anomia. Anomia is the technical word for tip-of-the-tongue syndrome when you can almost remember a word, but it just won’t quite come to you.
• The brain is much more active at night than during the day. Logically, you would think that all the moving around, complicated calculations and tasks and general interaction we do on a daily basis during our working hours would take a lot more brain power than, say, lying in bed. Turns out, the opposite is true. When you turn off your brain turns on. Scientists don’t yet know why this is but you can thank the hard work of your brain while you sleep for all those pleasant dreams.
