Right Brain VS Left Brain Functions

Right Brain VS Left Brain Functions

The human brain is divided into two distinct cerebral hemisphere connected by the corpus callosum which give as right brain VS left brain functions. The sides resemble each other but the functions of each side are distinctly different. While no one is really left brained or right brained only, unless a hemisphere is removed, it is quite interesting to see how people test. Broad generalizations are made in popular psychology about certain function on one side or the other. Actually, scientists continue to explore how some cognitive functions tend to be dominated by one side or the other, that is, how they are lateralized. The left side of your brain controls the right side of your body and vice verso for the right side. Different parts of the brains control different functions of the body.

Brain anatomy is very interesting and we know there are specific differences in the two sides. For instance, the lateral sulcus generally is longer in the left hemisphere than in the right hemisphere, but we don’t always see any functional differences. If a specific area of the brain is injured its functions sometimes can be assumed by another area of the brain.

"Split Brain" Experiments by Roger Sperry

In 1981, Roger Sperry won the Nobel Prize as he conducted called the “Split brain” experiments. A patient suffered from uncontrolled seizures and had an area of his brain removed by surgery in an attempt to control his illness, which was the corpus callosum. After the surgery the patient seemed to function normally as he could walk, talk and eat, however some astounding results occurred. They conducted tests individually on both sides of the body. For instance, the right eye and hand could name an object such as a pencil but could not explain what it was used for. The left eye and hand couldn’t name it but it could demonstrate how to use it.

According to Roger Sperry (1973), “The main theme to emerge... is that there appear to be two modes of thinking, verbal and nonverbal, represented rather separately in left and right hemispheres respectively and that our education system, as well as science in general, tends to neglect the nonverbal form of intellect. What it comes down to is that modern society discriminates against the right hemisphere.”

Mayo Clinic's Brain Mapping

Brain mapping is an advance neurosurgical procedure used to identity which areas of the brain controls various functions and this surgery is currently being studied at Mayo Clinic.

Typically mind mapping is used for patients with certain types of brain tumors or epileptic seizures when the diseased is found in areas of the brain that effect the patient’s vision, language and body movement. The patient is initially is initially put to sleep so numbing medication can be given, then awakened while the neurosurgeon stimulates the brain and they might be asked to move in a particular way or look at something specific. The patient is not in pain.A three-dimensional computer image of mapping software is used taking images before the surgery and during the surgery as a guide. The neurosurgeon removes the tumor or the damaged tissue which would then stop the patient from having multiple seizures. Highly trained and experienced neuroanesthesiologists specifically trained in this type of surgery are necessary so the patient feels no pain. Other specialist assesses the body movement, speech and language skills and a computer engineer manages the computer guided imagery.

Characteristics of Both Sides of Brain

While this very precise work is being done, there are still some characteristic thought to be more left or right sided. We are all a mixture of the characteristics from both sides.

Left brain characteristics: uses logic; detail oriented; facts rule; words and language; math and science; can comprehend; knowing; acknowledges; knows object name; reality based and practical.

Right brain characteristics: uses feeling; big picture oriented; imagination rules; symbols and images; intuition; appreciated; spatial perception; knows object function; fantasy based; presents possibilities; impetuous and risk taker

Summary

Also, particularly as we age, it is good to play mind games or use brain teasers to keep your mind sharp, as it needs exercise just as much as your body does. This is a website that gives you a free test at no cost: http://www.wherecreativitygoestoschool.com/vancouver/left_right/rb_test.htm

Since we live in a world that is hugely left-brained, we end up with a more material focus than a spiritual one. The language of the spirit is intuition, impressions, images, feeling, and pictures. It is interesting to look at your life habits, the way you relate to others and see if you can figure out which is a right brain VS left brain function

Do you know if you are predominantly a right brain or a left brian thinker?

Very interesting info. I voted that I am a right brain thinker and I know my husband is a left brain thinker - I think my daughter follows along with my husband. I find this interesting though because my daugther's brain sufferend damage when she was born but it seems she way more comprehends concrete info rather than abstract. So maybe it was more of her right brain that got damamged. But it is amazing to me that kids or anyone with brain damage it seems that they have other skills or abilities to make up for the damaged area. Anyway, great hub!

This is interesting that you wrote this article at this time. My daughter is studying this for her drawing class and has been sharing the information with me. Yesterday she even did some of the right brain/left brain tests on me. She also said that when you write you use your left side of the brain to spell, etc.. but the right side is the side that does the creating. When you get writers block, it is because the two sides are fighting with each other. Interesting!

You're absolutely right when you say that we live in a mainly left-brain biased world. At school when children in their early life are so creative, they seem to lose their natural creative ability as they progress through their schooling and it's a shame see this happen to many of them. It's great to have facts and knowledge but more importantly is the ability to use the imagination to resolve problems and challenges creatively.

I was more left-brained until my mid 30's but with mind-mapping and now writing poetry I'm now starting to develop more of my right side. It would be nice to be right and left brain balanced and that is goal I'm aiming for!

Thanks for sharing this very useful hub. Cheers!

Gosh, I almost missed this one, and it is one of my most favorite interests. I think the brain is the most awesome organ in the body. And imagine, we use only 5-7% of it. Why? I also did the test – for the 3rd time in my life – and was quite surprise. The last time I was 50-50, and now I am 60-40 (left dominant). I wonder how/why this happened? Did you know they regard music tuition as the best developer of both sides simultaneously – in order to become 50-50? Thank you so much for this hub, Pamela. I really appreciate this. Take care.

PS.: There are people – in the right side of their brains nothing is right, and in the left side nothing is left.

Jill Taylor is a brain scientist who had a stroke that disabled her left brain. She tells her story in her amazing TED conference video that had spread across the internet. Her book is "My Stroke of Insight".

The left-brain is also the seat of the ego. It is interesting to note that when she lost her ego, she found a certain amount of peace and she lost of her sense of time (no more rushing -- time didn't matter to her). The right-brain see the "big picture", while the left-brain is sequential. More about her story in Hub http://hubpages.com/t/bf859

jklahlou profile image

Your article is well written, however there is little lateralization of function that I know of other than language (Broca's and Wernickes area's).

Wikipedia: "Broad generalizations are often made in popular psychology about one side or the other having characteristic labels, such as "logical" for the left side or "creative" for the right. These labels need to be treated carefully; although a lateral dominance is measurable, both hemispheres contribute to both kinds of processes, and experimental evidence provides little support for correlating the structural differences between the sides with such broadly-defined functional differences."


Pamela99 profile image

Pamela99 3 years ago from United States Author

jklahlou, There is some truth to that, but Wickpedia is not considered the most reliable souce for accurate information. There are some proven anatomical differences between the two sides and Mayo Clinc's brain mapping has been helpful for neurosurgeons. I have heard stories where people had one side of their brain damaged and over time the other side is capable of taking over some new functions. I think scientist still have a lot to learn about the brain. I appreciate your comments.


jklahlou profile image

jklahlou 3 years ago

I agree Wikipedia should never be relied upon, but its a great heuristic. As a student of neuroscience I haven't been taught of any insofar other than a predominance of the language areas to be in the left hemisphere. It would be false to say that one side of the brain is for one thing and the other for another (analytic and creative), and has been falsified using neuroimaging techniques on humans (EEG & fMRI).

The areas brain can and have been mapped and their functions have been understood (at least partly).

The same point was made on the top comments on the YouTube video 'Left vs. Right brain education'.

I agree, scientists have a very long way to go in understanding the brain, something I wish (and hope) to do in the future. 'Neuroplasticity' is a magical thing, where the surrounding tissues take on the functions of a specific area of the brain that has been damaged and the person starts to recover.

Keep up the great writing!

Hi Pamela

This topic always fascinates me even though I have taken many classes on the subject and have those in my family who have had /have brain tumors.

The subject is particular interest as a teacher (even though I am retired I will always be one). We used many strategies and techniques involving fostering use of the whole brain. I learned specific physical activities that I believe helped my students to learn better. I may just be prompted to write about those experiences thanks to your inspiration. Angels are on the way to you today. ps
