The human brain is one of the most complex structures in the universe. It has more neurons than there are stars in the galaxy! Even though we know a lot about stars and planets, we still have much to learn about how our own minds work. The brain’s network of nerves, cells, and connections is incredibly intricate, which is why people often try to simplify its functions.
You’ve probably heard that the brain is divided into two halves: the left brain and the right brain. Many people believe that the left side is responsible for logical tasks like math, language, and facts, while the right side handles creativity, imagination, and emotions. This has led to the idea that people are either “left-brained” or “right-brained,” similar to being left or right-handed. For example, accountants and lawyers are often thought to be left-brained, while artists and musicians are considered right-brained.
However, this idea isn’t entirely true. Research shows that the brain isn’t as divided as people think. While the two sides do have different functions, they work together more than the left vs. right concept suggests. For instance, when solving math problems, the left side might handle the equations, but the right side helps with comparisons and estimations, which are also important in math.
The idea of left vs. right brain dominance came from the work of neuroscientist Roger W. Sperry, who won a Nobel Prize for his research. He studied patients with severe epilepsy and performed surgeries that cut the corpus callosum, the main connection between the two brain halves. His observations led to the popular belief in left and right brain dominance, but modern research has disproven this theory.
A study in 2013 used MRI scans on a thousand people and found no evidence that one side of the brain dominates specific functions. Instead, both sides work together to perform tasks. For example, when recognizing an object, the left side focuses on details, while the right side looks at the overall shape. This teamwork is essential for completing tasks effectively.
Further evidence against the left vs. right brain theory comes from extreme cases. Research shows that people can function normally with only half a brain. In 1923, surgeon Walter Dandy performed a hemispherectomy, a procedure that removes half of the brain, mainly in children with severe seizures. Amazingly, many of these patients developed normal memory, personality, and speech, with an 86% success rate in curing seizures. Although there are some drawbacks, like loss of eyesight and motor function on the opposite side of the body, this procedure shows the brain’s incredible ability to adapt and redistribute functions.
In conclusion, the idea of left and right brain dominance is a myth. There’s still so much to learn about the complexities of the human brain, and it’s exciting to think about what future discoveries might reveal!

Use clay or playdough to create a model of the human brain. Label the different parts and discuss their functions with your classmates. This hands-on activity will help you visualize the brain’s structure and understand how its parts work together.
Divide into two groups and hold a debate on the myth of left-brain vs. right-brain dominance. One group will argue in favor of the myth, while the other will present evidence against it. This will help you critically analyze the information and understand the importance of scientific research.
Research a real-life case of brain plasticity, such as a hemispherectomy patient, and present your findings to the class. Discuss how the brain adapted in this situation and what it reveals about the brain’s capabilities. This will enhance your understanding of brain plasticity and its implications.
Create a quiz with questions about the brain’s functions, the left vs. right brain myth, and brain plasticity. Use online tools to make it interactive and test your classmates’ knowledge. This activity will reinforce what you’ve learned and make studying fun.
In small groups, role-play different scenarios where the brain’s functions are at work, such as solving a math problem or creating art. Each member can represent a different part of the brain. This will help you understand how various brain regions collaborate to perform tasks.

This is a brain, one of the most complicated structures in the universe. There are more neurons in the human brain than there are stars in the galaxy, and we understand much more about the interactions of stars and planets than we do about the workings of our own minds. Given the complexity of the brain’s network of nerves, cells, and connections, many people tend to simplify its functions.
A common notion is that the brain is divided into two halves: the left brain and the right brain. It is often said that the left side is primarily responsible for logical functions such as mathematics, sequencing, language, and factual information, while the right side is associated with creativity, imagination, intuition, and emotional visualization. This has led to the idea that individuals are either left-brained or right-brained, similar to being left or right-handed. For example, accountants and lawyers are often labeled as left-brained, while artists and musicians are considered right-brained.
However, this dichotomy is not accurate. Research indicates that the brain is not as divided as commonly believed. While the two hemispheres have different functions, they work together in a more integrated manner than the left versus right concept suggests. For instance, while the left hemisphere may handle mathematical equations, the right hemisphere contributes to comparisons and estimations, both of which are integral to mathematics.
The notion of left versus right brain dominance originated from the work of Nobel Prize-winning neuroscientist Roger W. Sperry, who studied patients with severe epilepsy and performed a surgery that severed the corpus callosum, the main connection between the two hemispheres. His observations led to the popularization of the idea, but modern research has disproven this theory. A 2013 study involving MRI scans of a thousand individuals found no evidence of one hemisphere dominating specific functions; instead, both sides collaborate to perform tasks.
For example, when recognizing an object, the left hemisphere focuses on details while the right hemisphere considers the overall shape. This holistic approach means that both sides are essential for completing tasks effectively.
Further evidence against the left versus right brain theory comes from extreme cases. Research shows that humans can function normally with only half a brain. In 1923, surgeon Walter Dandy performed a hemispherectomy, a procedure that involves removing half of the brain, primarily in children with severe seizures. Remarkably, many of these patients developed normal memory, personality, and speech, with an 86% success rate in curing seizures. Although there are some drawbacks, such as loss of eyesight and motor function on the side opposite to the hemisphere removed, this procedure illustrates the remarkable plasticity of the brain, allowing functions to be redistributed to different areas.
In conclusion, the idea of left and right brain dominance is a myth, and there is still much to learn about the complexities of the human brain.
