Right Brain Vs. Left Brain: The Way The Two Sides Communicate Promotes Creativity

There is a culture of self-help books that like to talk about how essential the right brain is for creativity integration, and that the left brain is purely logical and can’t have much say in a creative process. Recent research is showing that this long-held belief is much more simplistic than we may have recently understood. Research from Duke University has found that highly creative people have more significant correlation of communication between each hemisphere of their brain. This means that the way the left side of the brain interacts with the right side, and vice versa, is what properly influences creative thought and action.

Statisticians David Dunson of Duke University and Daniele Durante of the University of Padova studied the white matter connections that the brain makes to find any conclusive evidence of these claims. They found over 68 separate brain regions in the averaged-aged college volunteer. The white matter of the brain typically resides underneath the outer grey matter and is composed of axons and wires that allow over a billion different neurons to connect and carry signals between the two.

Making The Connections

Neurologists were also present during the study as the exact processes of the brain were examined by looking at various tensor imaging, MRIs and other types of brain tests. Problem solving entitled divergent thinking was assessed to understand the importance of the two sides conversing with one another. The people who scored in the top 15 percent on the tests that were made strictly for creativity achieved the most connections between the right and left hemispheres.

The brain is much more interconnected than we think. Many of the differences that were found were in the frontal lobe which deals mostly with thinking through a problem or issue prior to taking any definitive action. Dunson also found that this specific approach could be used in order to predict the probability an individual is deeply inclined towards identifying as a highly creative person.

Searching For More Information

This new wave of thinking decides that instead of focusing solely on specific regions of the brain, that the best use of testing and what the data shows is the dance in conversation that both hemispheres do with one another in order to reach peak creativity. The researchers are now searching for any type of correlative information that can tell them if this type of connectivity matters or differs based on I.Q.

This type of testing can also potentially be used in the testing of Alzheimer’s disease and can have a hand in greater early detection. It would help to distinguish the forgetfulness and normal signs of aging with the early signs of the disease that can be devastating to family, friends and sufferers. These types of studying patterns can also be helpful when finding out more information about diseased brains – to better understand neurological conditions, mental illnesses, epilepsy, and overall health within the brain space.

If this type of information can be beneficial in the treatment of serious brain issues, such as coma or chronic traumatic encephalopathy – otherwise known as traumatic brain injury – it could be huge for the medical community and their ability to better treat these devastating issues. Additional research has to be done.

Food For Thought: What To Eat To Keep Your Mind Sharp


Purple Sweet Potatoes
Loaded with antioxidants just like orange and yellow sweet potatoes, the pigments in the purple variety give it some distinct advantages in promoting brain health. These pigments help preserve the integrity of blood vessels that transport oxygen to the brain that normally diminish as we age. Keeping these blood vessels in good working order will ensure a healthy supply of blood to the brain. The best results will come from eating one sweet potato twice a week with the nutrient rich skins intact.


Though not the primary reason for consumption of coffee among most people, it actually has the ability to protect the fat component of cells against oxidative stress. This creates a positive effect of protecting brain cells, as the human brain is made up of 60% fat. Home brewed coffee tends to have less caffeine than varieties bought in a coffee shop, and will be a better choice considering that the best benefits come from drinking 2-4 cups a day. If you’re sensitive to caffeine, drink less or drink decaffeinated coffee instead.


Ginger is a potent anti-inflammatory, and can preempt the manufacture of inflammatory brain chemicals, and potentially slow down the progression of inflammation related conditions like Alzheimer’s disease. A 500 milligram supplement capsule a day is the best dosage, but you can also add one teaspoon of fresh ginger or one half teaspoon of powdered ginger to a meal 2-3 times a week.


Most people that think of fish for their brain boosting omega-3 fatty acids usually think of salmon or mackerel. However, sardines are loaded with them and are also far less likely to be contaminated with mercury than larger fish. They’re also budget friendly, and conveniently canned and often require no cooking. Include 3-4 servings of omega-3 rich fish in your meals weekly. Be sure to trim the skin when cooking other fish, as that will also reduce mercury content.
