Neuroscience: "Brain Facts"
"Brain Facts"

"Some facts you might be interested in:
- The human brain, with roughly 100 billion neurons, can be equated to a computer with a 1,000,000,000,000 bit per second processor. Even more fascinating: by 2020, computers will be able to do this (according to Moore’s Law which has proven quite accurate in predicting how computer speeds will increase over time).
- The brain is not sensitive to pain, even though it processes pain signals.
- It only takes one week of learning to juggle in order for your brain structure to change. This is more evidence that the brain keeps growing.
- The amygdala – where intense, personal, long-term memories are stored – is also the place where fear is processed.
- Hyperthymestic Syndrome is a rare condition of a memory that is actually too good. Exemplified by Jill Price, the condition doesn’t mean you remember everything, and is different than a “photographic memory”. In Price’s case, she remembers every event in your life.
- Your brain uses less power than your refrigerator light! In a day, it only uses a bout 12 watts of power (the same as contained in two large bananas).
- Although the brain is only 3 per cent of the body’s weight, it consumes 17 percent of the body’s total energy.
- Frequent jet lag can damage memory. Because stress hormones are released during jet lag, they damage temporal lobe and memory.”
