How does your brain works?

Answer 1

In the brain there is one part of the brain that tells you what to do that part of the brain is the boss say if you are at a friends house and you were help cooking and the knife falls the message gose up to the boss and it tells it that the knife is about to fall on your foot the boss sends the message to the foot to tell it the knife is about to fall on the foot and it would tell the foot to move so the foot would not get hurt.

EDIT:

That is a good way to put it, but the brain is more complex and it is not fully understood, but we know it works, so we could use it for computer AIs. There is also a "disorder" that gets your brain to work as a whole instead of parts allowing the person to memorize a lot more stuff, think faster, learn better, and there was a video about a person who had it that knew 7 languages.
your brain has four receptors that are all sending signals throughout your body at the same time. This is why multi tasking is so hard for some people because once all four of these receptors are each focusing on a task you find it hard to add something else into the equation.

Answer 2

That is a very good question! You have about 100 billion cells in your brain. Each cell may be attached to some 100 to 1000 other cells by synapses. So you have about 1000 billion synapses in one cubic centimeter of brain cortex. Now you should be able to understand the complexity of the interconnections between the neurons. So when some nerve impulse come in brain via some sensory input, it travels through most complicated paths. For example the current flows from one neuron to next 1000 neurons. Which pass through 1000*1000 and then through 1000*1000*1000 neurons. You can have many more steps. Some are shorter and some are longer. Beauty of the process is that the current can pass through same neurons after next turn make it still more complicated. The number of permutations and combinations may be thousands of billions or trillions time more than the number of atoms in the whole universe. That is beyond the human intelligence to the imagine the same. This impulse generate the intellectual ability like thinking, reasoning, imagination and memory as well as the emotional response you get. Some basic instincts come there with life. How they act on your brain is also not known. There is feeling of self or ego. Where from it comes and how it integrates with functions of your brain is not known. Your knowledge about the functioning of human brain is very primitive. Great philosopher Socrates once said " I know one thing that I know nothing". It is very true even today!
