The brain is a monstrous, beautiful mess. Its billions of nerve cells - called neurons - lie in a tangled web that displays cognitive powers far exceeding any of the silicon machines
.
.The brain is the most amazing and complex organ in this universe and its research continues to throw up new facts that surprise¡¯s us.
.
.The brain is capable of being modified or improved even as we age. It is never used to its full capacity.
.
.1. The human brain has about 100,000,000,000 or 100 billion neurons . From the age of 35 years about 7000 neurons are lost daily.2. During early pregnancy the neurons in the fetus can multiplyat a rate 250,000 neurons/minute .
.2. During early pregnancy the neurons in the fetus can multiplyat a rate 250,000 neurons/minute .
.3. Brain is composed of 75 to 80% water . Dehydration can affect proper functioning of brain.
.4. Brain consists of 60% White matter and 40% Grey matter . White is the supporting matter and Grey is the thinking matter of the brain. If the brain was a computer the grey matter wouldbe the computer itself and the white matter its cables.
.5. Adult brain weighs about 3 pounds or 1300 to 1400 Grams . This is about 2% of the body weight if you weigh 150 pounds or 70 kgs. Sperm whale¡¯s brain weighs 7800 gms.
.6. Although the brain only accounts for 2 percent of our body weight but it consumes 20% of the oxygen that we breathe and roughly 20 percent of our daily calories .
.7. 15-20% of all blood pumped out of the heart goes directly to the brain.
.8. All the thinking in the brain is about electricity and chemicals . The brain is more active and thinks more at night than duringthe day.
.9. The brain itself is incapable of feeling pain . Once the skull is opened it is possible to operate on the brain with the patient awake.
.10. You can¡¯t feel your own tickleeither . The brain is smart enough to neutralize the sensation. The cerebellum sends a signal to rest of the brain of your intentions and as a result the sensation is ignored.
