Near-death experience: in our head?

 About death, life and brain.

It is called near-death experience (NDE) and for some, it is a proof that afterlife exists. Well-known and yet mysterious, near-death experience is a weird phenomenon. From a physiological point of view, your heart stops beating but you are not dead. But from the person’s point of view, strange things happen.

I am left-handed, what about you?

A matter of hand

Around 90% of the population use their right hand to write, 9% are left-handed and 1% is ambidextrous. Lefties earn on average 10% lower wages, and are dominant in creative and artistic carriers. How is that possible? Why are some people right-handed, others left-handed and a couple are both? What are the implications of such a random process and what are the outcomes?

The Human Brain: Why do we like it?

Around 100 billion neurons capable of 100 trillion calculations per second in only 1,195 cm3, weighting 1.5 kg, using 20% of our total daily energy along 162,500 km of connected “cables” processing 36,800 trillion bits of information per second. It is 2% of your body’s weight, but requires 20% of your oxygen supply and 20% of your blood flow.

The human brain is a huge calculator. As a matter of fact, the human brain is the most complex computational system ever known.

Computational is used here to describe the functioning of the brain since it deals with information and makes calculations out of it, it differs from computer in its uniqueness: while a computer treats only one information at a time, our brain treats them all together.

Welcome into the human brain.
