· The left hemisphere of the brain has 186 million more neurons than the right hemisphere.

· 750-1000ml of blood flow through the brain every minute or about 3 full soda cans.

· The brain can stay alive for 4 to 6 minutes without oxygen. After that cells begin die.

· Yawns wake up the brain: Yawning expands our pharynx and larynx, allowing large amounts of air to pass into our lungs; oxygen then enters our blood, making us more alert.

· Your cerebral cortex is about as thick as a tongue depressor. It grows thicker as you learn and use it.

· The human brain is the fattest organ in the body and may consists of at least 60% fat.

· Stopped growing. Your brain stopped growing at age 18.

· Once a human reaches the age of 35, he/she will start losing approximately 7,000 brain cells a day.

· You can't tickle yourself because your brain distinguished between unexpected external touch and your own touch.

· A small area in the brain called the amygdala is responsible for your ability to read someone else's face for clues to how they are feeling.

· Women tend to take longer to make a decision, but are more likely to stick with the decision, compared to men, who are more likely to change their mind after making a decision.

· Laughing at a joke is no simple task as it requires activity in five different areas of the brain.

· Music lessons have shown to considerably boost brain organization and ability in both children and adults.

· Cannibalism. Some research shows that humans carry genes that help protect the brain from prion diseases, or diseases contracted through eating human flesh, leading medical experts to believe that ancient humans may have eaten other humans.

· Women are twice as likely to be diagnosed with depression than men in the United States.
