The Brain
Have you ever wondered what is the most complex structure in the universe? here is the answer, it is your brain.

No other brain in the animal kingdom is capable of generating the kind of higher consciousness associated with human ingenuity, with our ability to make plans and write poetry. Yet the most complex structure in the known universe – as it is often described – is more mysterious than the least- explored regions of the deepest ocean.
The human brain is divided into two hemispheres, the left and right, connected by a bundle of nerve fibers called the corpus callosum. The hemispheres are strongly, though not entirely, symmetrical. The left brain controls all the muscles on the right-hand side of the body; and the right brain controls the left side. One hemisphere may be slightly dominant, as with left- or right-handedness.
The popular notions about "left brain" and "right brain" qualities are generalizations that are not well supported by evidence. Still, there are some important differences between these areas. The left brain contains regions involved in speech and language (Broca's area and Wernicke's area), and is also associated with mathematical calculation and fact retrieval, Holland said. The right brain plays a role in visual and auditory processing, spatial skills and artistic ability — more instinctive or creative things, Holland said — though these functions involve both hemispheres.
