Our brain has many functions. It does all that you have said. How? Because our brain has many different areas. These
areas are specifically designed for a certain function. And yes, we have not fully utilized our brain, so far I think we
only use 30% of it.
LOLz, its amazing how our brain is designed, both the in's and out's of it. I didn't study one full
semester of neuroanatomy for nothing!!! >_<
Lets have a simple example. For instance, someone orders you to "Raise your right hand"
http://www.ship.edu/~cgboeree/speechareas.gif --> Look for
reference!
Now, the command "raise your right hand" will travel through sound waves and will be received by our ears.
This sound will then be converted in to neural stimuli. This neural stimulus will then be collected at the primary
auditory complex (green) on the left hemisphere of the brain. But of course, it doesn't end there. In order for the
brain to understand the command, it has to be processed.
This collected neural stimuli is then transferred to Wernicke's Area (yellow). Think of it as a processor. Now the
command "Raise your right hand" is readily understandable by our brain. Let's say for instance, that we
complied with the command and we want to raise our right hand.
Processed data from Wernicke's area will now be brought to the frontal cortex. The frontal cortex will now plan out
and organize the necessary steps and movements to "raise your right hand" once the plan is perfect, it will be
sent to the Motor Cortex for execution.
And so we "raise our right hand" ^__^
But what if, for instance we DONT want to raise our right hand and we decide to tell that person "No, because who
are you to boss me around?!"
The frontal cortex will now make the appropriate steps and plans in order to execute our answer. Before proceeding to
the Motor Cortex for execution, it has one final checkpoint. Broca's Area (blue) is an area that produces speech
that follows the rules of grammar. Once the plan is perfect, execution!
Of course, these are just few of the things that the brain can do. If I explained everything, that take really long.

Nice to know stuff: XD
The left hemisphere of our brain is called the dominant hemisphere. It is what we use for speech, language, reading,
math, logic etc. The right hemisphere is for abstract, visual imagery, music etc.
Right handed people use 80% dominant hemisphere and 20% right hemisphere. While left handers use 60% dominant 40% right
hemisphere. Hmm...what about ambidextrous people? Well, we'd have to test our their "sidedness" in order
to categorize them to right or left. >_<
