The adult human brain weighs 3 lbs.
The average human brain is 140 mm wide
The human brain has about 100,000,000 neurons
If your brain looses blood for 8-10 seconds, you will lose
consciousness
Seafood makes your brain loose dementia, which is good for
your brain
WHITE AND GREY MATTER
Your brain is 60% white and 40% grey matter
Grey matter is made up of neurons, which gather and
transmit signals
White matter is made up of axons and dendrites which create
the network by which neurons send their signals
EINSTEIN’S BRAIN
• His brain is similar in size to a normal human’s brain but in
the region responsible for math and science, is 35% wider
• His brain was slightly larger than a normal brain because he
exercised it more
FACT PAGE 2:
 There are no pain receptors in the brain, so the brain can feel
no pain
 Scientists have discovered that men and women’s brains react
differently to pain, which explains why they may perceive or
discuss pain differently
 Boredom is caused by a lack of stimulation/excitement.

* Your brain is made up of 75% of water
* Your brain uses 20% oxygen and 20% of the blood circulating
in your body
* While awake, your brain generates between 10 and 23 watts
of power-or enough energy to power a light bulb
* Children who learn two languages before the age of five alters
the brain structure and adults have a much denser grey
matter
DREAMS EXPLAINED AND COMPARED
• In the 1940’s and 50’s black and white dreams were very
common (black and white television, etc.)
• Dreams could be memories or reminders, but acted out,(we don’t

• Dreams, on average, last 15-20 mins.
• Nightmares are caused by stress, pressure, or eating before bed.
(except cheese, it helps you sleep)

Lack of sleep can hurt your brain
Info in your brain travels 268 mph.
Humans have at least 70,000 thoughts per day
London taxi drivers have a larger than normal hippocampus
than most people. Especially the people that have been on the
job longest. The study shows that as people memorize more
info, that part keeps growing.
Fact Page 6 (last page)
• There are about 100,000 miles of blood vessels in the
brain
• Those who are lefty/ambidextrous have a corpus
collosum(the part that bridges the two halves) that is
about 11% larger than those who are right-handed
• Your brain stops growing, in size, at age 18
• The brain’s storage capacity is 256 exabytes(or 256
billion gigabytes). This is the equivalent to 1.2 billion
average PC hard drives, enough CD’s to make a stack
that can reach the moon, or 15 libraries for every person
on the planet!!!

Illusions explained
∞These illusions are all just pictures. Your brain
takes a shortcut so they look like they are
moving. Your brain does not take all of that
time. That is called fast thinking. Fast thinking
takes place when your brain tries to figure out
things fast. It makes illusions look like
illusions.
