You can’t hear phone
conversations in noisy rooms – The brain can’t distinguish background noise
from the voice on the phone.
3.
Yawning actually wakes
you up – Yawning gets more air into the lungs, thus increasing oxygen to the
brain.

We’re hardwired to
remember annoying songs – ‘Sequence recall’ to learn daily routines also lets
songs get stuck in our heads.

The brain uses less
power than a refrigerator light – The brain uses 12 watts of power – 17% of the
body’s energy.
6.
Frequent jet lag can
damage memory – Stress hormones released during jet lag can damage the temporal

7.
Altitude makes the
brain see strange visions – Oxygen deprivation is likely to interfere with
visual and emotional processing.
8.
Shoot-’em-up computer

Your brain uses 20% of
the total oxygen in your body.

Studies show that
brain waves are more active while dreaming than when you are awake.
16.
Excessive stress has
shown to alter brain cells, brain structure and brain function.
17.
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.
18.
Reading aloud and
talking often to a young child promotes brain development.
19.
