Brain Facts


1: Women are twice as likely to be diagnosed with depression than men in the United States.
2: The human brain has about 100,000,000,000 (100 billion) neurons.
3: From all the oxygen that a human breathes, twenty percent goes to the brain.
4: People who ride on roller coasters have a higher chance of having a blood clot in the brain.
5: Once a human reaches the age of 35, he/she will start losing approximately 7,000 brain cells a day. The cells will never be replaced.
6: It is not possible to tickle yourself. The cerebellum, a part of the brain, warns the rest of the brain that you are about to tickle yourself. Since your brain knows this, it ignores the resulting sensation.
7: In America, the most common mental illness is Anxiety Disorders.
8: Your brain is 80% water.
09: Your brain is more active and thinks more at night than during the day.
10: Nerve impulses to and from the brain travel as fast as 170 miles (274 km) per hour.
11: 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.
12: When you were born, your brain weighed about 350-400g and you had almost all the brain cells you will ever have. In fact, your brain was closer to its full adult size than any other organ in your body!
13: Your brain is about 2% of your total body weight but uses 20% of your body's energy.

When one tickles his penis, it definitely reacts.

I'am sure that only happens with your own Serious Sam Junior.

10: Your brain is more active and thinks more at night than during the day.
FALSE ONLY DURING REM SLEEP... which is only 20% of total sleep. And during that time its EQUALLY active.. not greater.
Thus the same BETA waves in REM + Awake


Only during REM Sleep (and awake) = Beta waves

Stage 1-4 Sleep (Alpha, Theta, Delta, SleepSpindle KComplex) = Less active

I had to memorize activity and brainwave order for usmle steps exam a couple of months back lol...

BATS DRINK BLOOD lol... Beta(awake) Alpha Theta Sleepspindle/KComplex Delta Beta(REM)
Beta are awake and REM both...

Far more interesting fact...

CLINICAL DEPRESSION = MUCH MUCH More REM SLEEP...

Depressed people have nearly 50% greater total REM sleep...

So they are more active in sleep then non-depressed people...
