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.
11) Children who learn two languages before the age of five alters the
brain structure and adults have a much denser gray matter.
12) Information can be processed as slowly as 0.5 meters/sec or as fast as 120 meters/sec (about 268 miles/hr).
13) While awake, your brain generates between 10 and 23 watts of power–or enough energy to power a light bulb.
14) The old adage of humans only using 10% of their brain is not true. Every part of the brain has a known function.
15) A study of one million students in New York showed that students who
ate lunches that did not include artificial flavors, preservatives, and
dyes did 14% better on IQ tests than students who ate lunches with
these additives.
16) For years, scientists believed that tinnitus was due to a function
within the mechanics of the ear, but newer evidence shows that it is
actually a function of the brain.
17) Every time you recall a memory or have a new thought, you are creating a new connection in your brain.
18) Memories triggered by scent have a stronger emotional connection, therefore appear more intense than other memory triggers.
19) Each time we blink, our brain kicks in and keeps things illuminated
so the whole world doesn't go dark each time we blink (about 20,000
times a day).
20) Laughing at a joke is no simple task as it requires activity in five different areas of the brain.
21) The average number of thoughts that humans are believed to experience each day is 70,000.
22) There are two different schools of thought as to why we dream: the
physiological school, and the psychological school. While many theories
have been proposed, not single consensus has emerged as to why we dream.
Some researchers suggest that dreams serve no real purpose, while other
believe that dreaming is essential to mental, emotional and physical
well-being. One theory for dreaming suggests dreams serve to clean up
clutter from the mind.
23) The Hypothalamus part of the brain regulates body temperature much
like a thermostat. The hypothalamus knows what temperature your body
should be (about 98.6 Fahrenheit or 37 Celsius), and if your body is too
hot, the hypothalamus tells it to sweat. If you're too cold, the
hypothalamus makes you start shivering. Shivering and sweating helps get
your body's temperature back to normal.
24) Approximately 85,000 neocortical neurons are lost each day in your
brain. Fortunately, this goes unnoticed due to the built-in redundancies
and the fact that even after three years this loss adds up to less than
1% of the total.
25) Differences in brain weight and size do not equal differences in
mental ability. The weight of Albert Einstein's brain was 1,230 grams
that is less than an average weight of the human brain.
26) A living brain is so soft you could cut it with a table knife.
27) There are about 100,000 miles of blood vessels in the brain.
28) London taxi drivers, famous for knowing all the London streets by
heart, have a larger than normal hippocampus, especially the drivers who
have been on the job longest. The study suggests that as people
memorize more and more information, this part of their brain continues
to grow.
29) The brain can live for 4 to 6 minutes without oxygen, and then it
begins to die. No oxygen for 5 to 10 minutes will result in permanent
brain damage.
30) Our brain often fools us. It often perceives things differently from
the reality. Look at those pictures. Square A and B are actually the
sameshade of gray.
