Our universe is full of wonders: from the invisible reactions that happen between atoms to the astounding pictures of galaxies.

Everything we see has its unique reason to exist.

Therefore, some people may ask themselves: which is the most incredible thing in our reality?

Obviously, the answer changes between one person to another.

Nevertheless, I'm sure many of us would agree that there's something that stands out because of its excellence.

And the most impressive fact is that it is inside us.

The human brain is the central machine of every human being.

Physiologically, it is an organ located in the head, protected by the skull, a hard structure that consists of twenty-two bones.

Although it has the same general structure as with other mammals, the human cerebral cortex is far more developed; and its size, in relation to the whole body, is much bigger.

Our brain is divided in two hemispheres, each one with many regions.

These regions, denominated "lobes", were originally purely anatomical in nature, but as neuroscientists have studied them more, they have discovered that each lobe has many important functions for our body.

This is true to the extent that a large article would be needed to describe each lobe.

The complexity of the brain lies in its wide array of functions.

One of the most fascinating to think about is cognition.

Analyzing and understanding the relationship between our brain and our mind (that is, between what we can see and what we can't), has always been a challenge for physicians, scientists and philosophers.

Just think of it: how can abstract processes, like thoughts or emotions, be implemented by physical strucutures such as neurons or synapses?

Of course, this topic would need deeper article to be explained; maybe even a complete book.

Even when an average brain weighs 1.4 kg (2% of the body weight), it is indeed the most fascinating and complex thing we can admire in this reality.

No one will ever be able to make a machine with such perfect and marvelous mechanisms.

For example, just think about language learning.

The processes of understanding and applying what we learn in a new language are surprisingly amazing.
