Left brain vs Right brain
The longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum. The hemispheres exhibit strong, but not complete, bilateral symmetry in both structure and function. For example, structurally, the lateral sulcus generally is longer in the left hemisphere than in the right hemisphere, and functionally, Broca's area and Wernicke's area are located in the left cerebral hemisphere for about 95% of right-handers, but about 70% of left-handers. Broad generalizations are often made in "pop" psychology about one side or the other having characteristic labels, such as "logical" for the left side or "creative" for the right. These labels are not supported by studies on lateralization, as lateralization does not add specialized usage from either hemisphere. 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.(Wikipedia)

Lateralization of brain function
Lateralization of brain function.
The human brain is divided into two hemispheres–left and right. Scientists continue to explore how some cognitive functions tend to be dominated by one side or the other; that is, how they are lateralized.

Understanding the Myth of Left Brain and Right Brain Dominance.
What Is Left Brain - Right Brain Theory?
According to the theory of left-brain or right-brain dominance, each side of the brain controls different types of thinking. Additionally, people are said to prefer one type of thinking over the other. For example, a person who is "left-brained" is often said to be more logical, analytical, and objective, while a person who is "right-brained" is said to be more intuitive, thoughtful, and subjective. In psychology, the theory is based on what is known as the lateralization of brain function.
In one study by researchers at the University of Utah, more 1,000 participants had their brains analyzed in order to determine if they preferred using one side over the other. The study revealed that while activity was sometimes higher in certain important regions, both sides of the brain were essentially equal in their activity on average.
While the idea of right brain / left brain thinkers has been debunked, its popularity persists.
