The preference to use one brain region more than others for certain functions, which scientists call lateralization, is indeed real, said lead author Dr. Jeff Anderson, director of the fMRI Neurosurgical Mapping Service at the University of Utah. For example, speech emanates from the left side of the brain for most right-handed people. This does not imply, though, that great writers or speakers use their left side of the brain more than the right, or that one side is richer in neurons.
There is a misconception that everything to do with being analytical is confined to one side of the brain, and everything to do with being creative is confined to the opposite side, Anderson said. In fact, it is the connections among all brain regions that enable humans to engage in both creativity and analytical thinking.
Even though the right hemisphere of the brain is creative and dare worthy, the left brain is more organized and it dos not do stupid things that it knows that the body shouldn't do. Also, you should only use the right side of the brain for only playing w/ your friends or to clean your bedroom/work space.
The differences between the two sides of the brain have been largely overstated in the field of neuroscience. A number of recent studies have shown how incorrect the side view of brains has been - something that's unsurprising, considering that a person can survive with only one side of their brain.
