According to some, the most sophisticated and complex device ever made by made humans is the International Space Station (ISS). Without any doubt, the ISS is a mind-blowing piece of technology any time and any day. However, how will you feel if you realize that there is another object that weighs just a few kilograms and has a sophistication and complexity that is far more than that of the ISS?

Of course, you will be dazzled and puzzled. However, you do not need to be, as you possess one of these masterpieces of technology  -the human brain. The brain is unarguably the most complex piece that humanity has come across. With its billions and billions of neuronal connections that fire countless signals in one second and coordinate all the activities of the human body, the brain is to say the least, staggering.

For decades, scientists and researchers have tried their very best in an attempt to understand the workings of this seemingly convoluted blub of fat but we are left with more questions than answers. Even with all the technological wizardry of the 21st century, much is still unknown about the computer. Supercomputers that calculate billions of calculate billions of calculations per second pale in significance when compared with the human brain.

In addition, one other thing that must be stressed is the fact whenever this piece of advanced technology is faulty, as in various neuropsychiatric disorders, there is always very little, if any that can be done. That is the main reason why neurosurgery, neuropsychiatry and neurology happen to be the most challenging areas of medicine. The reason is the brain, the source of incredible complexity. Although scientific researches are still going on trying to understand the brain, it is quite clear that it will be a mystery to us for quite a long period of time.
