Brain is the central organ of the human body. It is extremely complex and sophisticated. The functions of the brain were found by the ancient Egyptians and Greeks in 400 BC. It was Hippocrates who first discovered that brain played an important role in sensation and intelligence. Nowadays, everyone understand the importance of having the brain, but most of us don’t know much about it, so here are some interesting facts for you.

1) There are no pain receptors in the brain, so the brain can feel no pain.

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

3) Neurons develop at the rate of 250,000 neurons per minute during early pregnancy.

4) Humans continue to make new neurons throughout life in response to mental activity.

5) Alcohol interferes with brain processes by weakening connections between neurons.

6) Altitude makes the brain see strange visions – Many religions involve special visions that occurred at great heights. For example, Moses encountered a voice emanating from a burning bush on Mount Sinai and Muhammad was visited by an angel on Mount Hira. Similar phenomena are reported by mountain climbers, but they don’t think it’s very mystical. Many of the effects are attributable to the reduced supply of oxygen to the brain. At 8,000ft or higher, some mountaineers report perceiving unseen companions, seeing light emanating from themselves or others, seeing a second body like their own, and suddenly feeling emotions such as fear. Oxygen deprivation is likely to interfere with brain regions active in visual and face processing, and in emotional events.

7) Reading aloud and talking often to a young child promotes brain development.

8 ) Information travels at different speeds within different types of neurons. Not all neurons are the same. There are a few different types within the body and transmission along these different kinds can be as slow as 0.5 meters/sec or as fast as 120 meters/sec.

9) The capacity for such emotions as joy, happiness, fear, and shyness are already developed at birth. The specific type of nurturing a child receives shapes how these emotions are developed.

10) The left side of your brain (left hemisphere) controls the right side of your body; and, the right side of your brain (right hemisphere) controls the left side of your body.
