Is this blog for everyone?

This blog is designed to simplify workings of the human brain to a level that can be understood by anyone who is prepared to make the necessary effort. No prior knowledge of any subject is required to understand it.

That sounds absurd… How can someone understand workings of the human brain, which is the most complex object in the observable universe, without prior knowledge of any subject?

Human brain is complex. Not complicated.

According to the dictionary, something is complex when it is composed of many different but related elements and something is complicated when it is difficult to figure out. Things that are complex are often complicated and vice versa, but not necessarily.

As explained in the introduction, it is true that the brain is highly complex structurally, but functionally, it is a system that drives it, the complexity of which need not be proportional to the complexity of its structure.

As an analogy, let’s compare countries by their population. Even when United States’ population is four times that of Hong Kong and India’s population is four times that of United States, there is not much difference in the complexity of the system that drives them, i.e. the system of government.

Thus, the general impression that brain functions in an infinitely complex manner is wrong.

What’s more, brain’s complexity is further contributed by the fact that its elements interact with each other through mechanisms which are driven by a system. Fortunately, both the mechanisms and the system are simple, because they have evolved in a step-by-step and gradual manner for thousands of generations through the process of natural selection and are not a product of deliberation of an intelligent designer.

To understand how the brain works, one must understand such mechanisms and the system that drives them, which are explained in this blog.

To answer the question, this blog is for anyone who has a brain.
