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.

Every time we learn something ,we are creating new connections (neural pathways) in our brain.
our brain has 70 to 100 billion neurons (nerve cells), the number of which grows when we are
learning new things.

When you yawn after someone else also did this ,you did this because you have cells in your brain
called mirror neurons. If this part of the brain is damaged, a person finds it hard to socialize
and communicate with others.

our brain is 75% water , that’s why, when we are dehydrated, our brain slows down and becomes
fuzzy long before we get the actual physical symptoms of thirst.

Information travels at different speeds within different types of the neurons. transmission
along these neurons can be as slow as 0.5 meters/sec or as fast as 100 meters/sec, this is why
sometimes our brain recall information instantly, and sometimes it takes a little longer.

While awake, our brain generates between 10 and 23 watts of power or more than energy to power
a light bulb.

scientists believed that tinnitus ( a condition that causes ringing or buzzing in the ears)was due
to a function within the mechanics of the ear, but new research shows that Tinnitus is actually
produced by an unfortunate confluence of structural and functional changes in the brain.

Laughing at a joke is not simple task as it requires activity in five different areas of the brain .
Humans can’t tickle themselves because the brain distinguishes between unexpected external touch and
a person’s own touch .
a person’s own touch .
There are no pain receptors in the brain, so the brain can feel no pain.
once we lose our neurons,we can’t get them back. It’s true, but we can grow new ones. Learning
to speak another language and developing a new skills are best ways to give our neurons a boost.

our brain consists of 60% white matter and 40% grey matter.White matter is actually pink color, it’s
made up of axons and dendrites, it’s responsible for communication between different brain regions
via neural networks. Grey matter is actually pink too and it’s primarily associated with processing and cognition.

our brain uses 20% of oxygen in your body. that’s why it feels good when we take a breath of fresh air.
our brain is the most energy consuming part of body . The brain represents only 2 percent of the body
weight, but it uses up to 20 percent of the body’s energy to fuel electrical impulses and for cell-health maintenance

The left side of our brain called left hemisphere,it controls the right side of our body and the right
side of our brain called right hemisphere, it controls the left side of our body.
