Right Brain, Left Brain, Whole Brain

By Victoria W. McCurdy


It's unfortunate but true, and probably due to our tech-driven, scientifically orientated world, that when I tell people I write poetry for a living, I'm likely to hear the question, "But what's it for? What does it do?" And that's a puzzler when it comes to literature and poetry. To those of us who love it, it's perfectly obvious what it's "for."

There are specific activities that may stimulate the right or left brain.Activities that stimulate the left brain are solving crossword or word search puzzles, performance of learned tasks, language usage, both comprehensive and expressive, analytical information, problem solving, and recalling new information. Geometric or spatial memory, hand gestures, writing one's name, classifications of pictures or words into categories, recalling complex narratives, recognizing someone you have met, and name recognition are also all left brain activities.

Left brain, right brain... Uh, what? We've all heard this division-of-the-brain theory many times. Personally, I can never remember which way around it goes, but then that probably means I'm a bit of a right-brainer! It all has to do with the way our brains process information, and which tasks get assigned to which parts of the brain, with the right brain supposedly being more 'artistic,' and the left being more of a computer.

First, let's take a look first at how the frontal lobes of the brain's neocortex work. This is the part of the brain right behind your forehead. The left side and the right side are connected by a fibrous band in the middle called the "corpus callosum." In order to use both sides of the brain, neurons on the left side have to be connected to neurons on the right side. In other words, the electrical charge between brain cells has to pass across the corpus callosum. O.K. that's the theory part.

Our memories, our verbal skills and our understanding of meaning are spread through different areas of our brains, a complex network that we draw on without even - well - thinking! And this is where poetry finds a remarkable niche. Why do children memorize far more easily when they are given information in rhyme? Why do YOU still remember songs and poems that you learned when you were small? You probably even still use some of those mnemonics, and you're definitely passing them on to your own children, helping them to learn nursery rhymes and the letters of the alphabet that way.

he Nobel award winner of the year 1981, Roger W. Sperry revealed, we could lessen the effect of seizures by cutting the corpus, which is connects the two hemisphere. The right side of the brain is regarded as wonderful on creative tasks. Right brained people can very easily perform task like expressing emotions, playing musical instruments, recognizing images, faces, and colors, revealing strong intuitive, can read emotions and command on creativity. And the left brained are amazing in logical thinking, questioning, language and numerical subjects, and crucial thinking.

It would seem that our brains have been programmed for this kind of thinking since before anyone even thought of writing anything down. After all, how are you going to pass down the tribe's history to the next generation, unless you turn it into an epic song or poem that people can remember, one verse at a time? Entire moral codes and genealogies were passed on in this manner until came up with the written word, and though we can now access all kinds of words on the internet with a flick of a mouse button, our brains still crave the stimulus that poetry gives, especially when it's spoken out loud.

Visual stimulation from the left side in a checkerboard pattern using different colors comes up through the optic pathway to the brain stem and up to the right brain. The T.E.N.S. unit set at subthreshold stimulates large diameter nerves which fire up to the cerebellum and to the opposite brain.
