mind

1. It can store an estimated 2,500,000 gigabytes
According to Paul Reber, Professor of Psychology at Northwestern
University, the human brain can store an estimated 2,500,000
gigabytes. That’s equivalent to 300 years worth of TV shows.
[Scientific American]
2. The human attention span is shorter than a goldfish
Research shows that the average attention span has decreased by
an average 12 minutes over the last 10 years. Today, the human
attention span is shorter than a goldfish. [Time] Studies have
even shown some links between device multi-tasking — for
example, if you’re scrolling through social media while watching
TV — and declining attention spans.
3. The average weight of the adult human brain is three pounds
On average, the adult brain weighs three pounds. For reference,
this is comparable to how much a cantaloupe weighs. [National
Geographic]
4. Memories are stored for both short-term and long-term use at
the same time
Neuroscientists have known for a long time that the hippocampus
stores short-term memories. However, a recent study revealed
that while short-term memories are formed in the hippocampus,
they are simultaneously stored in another part of the brain for
long-term memories.
5. Vitamin B1 can help improve short- and long-term memory
Vitamin B1 is essential to producing the brain chemical
acetylcholine, which is needed for concentrating and storing
memories. An Australian study revealed that those who consumed
B1 supplements and folic acid for two years improved long and
short-term memory. [Huffington Post]
6. Easy access to information can make it harder to remember
Being able to quickly access information—i.e. via our borderline
invincible Internet—actually makes it harder to remember. The
harder we work to access data, the more likely we are to
remember. [Huffington Post]
7. Memories start forming in the womb
Memories start forming in the womb, as this is a critical time
for brain development. Memory recall can occur as early as four
months into pregnancy. [ABC]
8. It uses 20% of the body’s total oxygen and energy
The brain uses 20 percent of the body’s total oxygen and energy,
which travels to the brain through blood vessels. Nerve cells in
the brain need a lot of energy; without adequate oxygen and
energy to the central nervous system tissue, one can suffer
impaired brain functions and neurological disorders. [Scientific
American]
9. It’s composed of 73% water
The brain is 73 percent water. It only takes 2 percent
dehydration to affect your attention and memory. [Daily Mail]
10. Sweating can temporarily shrink the brain
An hour and a half of sweating can temporarily shrink brain size
as much as one year of aging does. [Daily Mail]
11. Five minutes without oxygen can cause brain damage
Five minutes without oxygen can lead to brain cells dying, which
causes brain damage. [Medical Daily]
12. It generates 12-15 watts of electricity
The brain generates between 12 and 25 watts of
electricity—that’s enough to power a low wattage light bulb!
[National Geographic]
13. Neurons travel 150 mph in the brain
Neurons travel 150 mph in the brain. Different types of neurons
move at different speeds - for example, pain signals move much
slower than other ones. [National Geographic]
14. Those who take a quiz twice are 65% more likely to remember
the facts
Those who take a quiz after its revision are 65 percent more
likely to remember the facts. [BBC]
15. Learning new things increases gray matter in the brain
When we learn something new, our brain forms new connections
between neurons; this then increases visible gray matter in the
brain. [BBC]
16. Memory is prioritized by emotion
Memory is prioritized by emotion. But this also means that a lot
of our “memories” are unintended flawed fiction. [New Yorker]
17. Emotions can alter our brain chemistry
Similarly to the above fact, emotions drastically alter our
brains. The chemical reactions stirred by feelings can be
physically seen in brain scans and studies of gray matter.
[Huffington Post]
18. It has an average of 50,000-70,000 thoughts a day
The average brain has between 50,000 and 70,000 thoughts a day.
Upsettingly, the majority (an estimated 60-70 percent) of the
thoughts are negative. [Huffington Post]
19. More than 100,000 chemical reactions take place in the brain
every second
With roughly 100 billion brain cells, more than 100,000 chemical
reactions take place in the brain every second. [National
Geographic]
20. When intoxicated, it can’t form memories
When intoxicated, the brain is incapable of forming memories. So
no, you didn’t “forget” what happened last night. The memory
simply was never formed. [Daily Mail]
21. Practicing recollection can help PTSD
Practicing recollection can help aid PTSD. There are a variety
of psychological treatment methods that mental health care
providers use to help those suffering from PTSD safely confront
and cope with traumatic experiences. [Smithsonian]
22. Its texture and consistency is comparable to tofu
The texture and consistency of the human brain is comparable to
tofu. This isn’t too surprising, given that it’s made up
primarily of gray and white matter, as well as water. [National
Geographic]
23. It starts slowing at around 24 years old
Research shows that the cognitive speed of your brain starts
slowing down when you're around 24 years old. [Time]
24. 95% of all decisions are subconscious
95 percent of all decisions take place in the subconscious mind.
This means that the vast majority of our actions and behaviors
occur due to brain activity that lies beyond our conscious
awareness. [Science Daily]
25. The brain itself cannot feel pain
Although pain is processed in the brain, the organ itself cannot
feel pain. This is why brain surgeries can occur while a patient
is awake, without discomfort. [Time]
The list goes on and on. As more research is conducted, and we
learn more about the human brain’s capabilities, we also learn
how to keep our minds sharp. Find out how we recall memories and
how the brain changes when you learn.
As good as the brain is at turning short-term memories into
long-term ones, it’s still important to keep those memories
preserved for future generations. That’s why Legacybox helps you
to digitize your memories - whether you have tapes, film,
photos, or audio recordings, we’re here to help.
