The concept of right vs. left brain is popular in contemporary culture, with many people believing that they are either left-brained or right-brained and that this determines their personality, skills, and preferences. You’ve probably come across various posts, quizzes, and pictures on the internet that claim to inform you about your dominant brain hemisphere. While there is scientific evidence to support the idea of hemispheric specialization in the brain, the popular understanding of the right vs. left brain is often oversimplified and misleading.
One way to think about the difference between the left and right hemispheres of the brain is to consider how they process information. The left hemisphere tends to process information in a linear, step-by-step manner, while the right hemisphere processes information more holistically and all at once. This means the left hemisphere is better suited for tasks requiring detailed analysis, such as reading a text or solving a math problem. In contrast, the right hemisphere is better suited for tasks that require seeing the big picture, such as understanding a complex relationship or interpreting a work of art. Thus, the idea that the two sides of the brain are associated with different functions has become deeply ingrained in popular culture, with the left side of the brain being associated with analytical thinking and the right side of the brain being associated with creativity and intuition.
The idea of the left brain/right brain split can be traced back to the 19th century when researchers first discovered that a bundle of fibers, called the corpus callosum, connected the two hemispheres of the brain. However, it wasn’t until the mid-20th century that this concept gained widespread attention, partially owing to the work of neuroscientist Roger Sperry. According to Sperry, the human brain has one side that is more dominant and determines your personality, thoughts, and behavior. Sperry and his colleagues conducted groundbreaking research in the 1960s and 1970s that demonstrated that the brain’s two hemispheres have different functions. For example, they found that patients who had undergone a split-brain operation, in which the corpus callosum is severed, could perform different tasks with each hand, depending on which hemisphere of the brain was dominant for that task. These findings led to a surge of interest in the left brain/right brain split, and the idea that the two hemispheres of the brain are associated with different functions became widely accepted. However, the reality is more complex than this simplistic dichotomy would suggest.
Despite these complexities, the left brain/right brain split remains a useful framework for understanding the specialized functions of the two hemispheres of the brain. To explore some of the differences between the left and right hemispheres of the brain and how these differences contribute to our cognitive abilities, continue reading.
An Overview
The differences between the left and right hemispheres can also be seen in how they communicate. The two hemispheres are connected by a thick bundle of nerve fibers called the corpus callosum, allowing communication between the brain’s two sides. However, some research has suggested that these two hemispheres may not communicate equally. For example, a study published in the journal Cerebral Cortex found that the left hemisphere was more active than the right hemisphere during a language task. In contrast, the right hemisphere was more active than the left hemisphere during a spatial task. Another way to think about the difference between the left and right hemispheres is to consider their specialized areas of the brain. For example, the left hemisphere is specialized for language processing, and it contains Broca’s and Wernicke’s areas, which are responsible for producing and understanding language, respectively. The right hemisphere, on the other hand, contains specialized areas for visual-spatial processing, such as the parietal lobe and the occipital lobe. These areas are responsible for recognizing patterns, interpreting visual information, and understanding spatial relationships.
It’s important to remember that studying the differences between the left hemisphere of the brain and the right hemisphere of the brain is just one way of thinking about brain function. The brain is an incredibly complex and multifaceted organ, and our understanding of its workings is still evolving. However, by exploring the differences between the left and right hemispheres of the brain, we can gain a greater appreciation for the incredible complexity and versatility of this remarkable organ. Although there are differences between the left and right hemispheres, it’s important to note that these differences are not absolute. Both hemispheres are involved in most cognitive processes and work together to allow us to process information and make decisions.
Functions of The Left Half vs the Right Half of the Brain
The left hemisphere of the brain is responsible for a wide range of functions, including language processing, logic and reasoning, mathematical computation, and critical thinking. This hemisphere is associated with linear thinking and analytical skills, making it well-suited for tasks that require careful analysis and attention to detail. The left hemisphere is also responsible for controlling the right side of the body and is involved in fine motor skills. One of the most well-known functions of the left hemisphere is language processing. People with damage to the left hemisphere may experience difficulty with language processing, such as a condition called aphasia, which can affect their ability to speak, write, or understand language.
The left hemisphere is also involved in mathematical computation and critical thinking. This hemisphere is responsible for processing and analyzing information, making logical deductions, and understanding cause-and-effect relationships. People with strong left hemisphere dominance tend to be analytical and detail-oriented and are often drawn to careers in science, technology, engineering, and mathematics (STEM).
In contrast, the brain’s right hemisphere is associated with creative thinking, artistic expression, and spatial reasoning. This hemisphere is involved in recognizing patterns, understanding metaphors, and processing information in a holistic, intuitive manner. The right hemisphere is also responsible for controlling the left side of the body and is involved in gross motor skills.
One of the most well-known functions of the right hemisphere is spatial reasoning. This hemisphere is particularly well-suited for tasks requiring spatial awareness, such as reading maps, solving puzzles, and understanding complex diagrams. People with strong right hemisphere dominance tend to be creative and artistic and are often drawn to music, art, design, and writing careers. The right hemisphere is also involved in recognizing patterns and making intuitive connections. This hemisphere is responsible for processing information in a holistic manner, allowing us to see the “big picture” and make connections between seemingly unrelated pieces of information. People with strong right hemisphere dominance tend to be creative and innovative thinkers and are also often drawn to careers in fields such as advertising, marketing, and entrepreneurship.
Theories About “Left-Brained” and “Right-Brained” People
“Left-brained” individuals are said to be analytical and logical, while “right-brained” individuals are said to be creative, intuitive, and artistic. One of the most common examples of this theory is that people who are good at math and science are “left-brained,” while creative and artistic people are “right-brained.”
However, while certain aspects of math and science, such as processing numerical information and understanding cause-and-effect relationships, are associated with the left hemisphere of the brain, creativity, and artistic expression involve a wide range of cognitive processes that are not localized to a single hemisphere.
Right-brained people are said to be carefree ‘big thinkers.’ They look at the world in highly subjective yet intuitive terms. Meanwhile, left-brained people are thought to be more methodical and detail-oriented. They are ruled by logic and are highly calculative.

Does the Scientific Research Back Up These Theories?
While there is some scientific evidence to support the idea that different cognitive functions are localized to different areas of the brain, the notion that people can be neatly divided into “left-brained” and “right-brained” categories is largely a myth. Moreover, while certain personality traits, such as analytical thinking and attention to detail, may be associated with left hemisphere dominance and creativity and intuition with right hemisphere dominance, research has not found consistent correlations between personality traits and hemispheric dominance. The idea that people can be neatly divided into “left-brained” and “right-brained” categories oversimplifies the complex interplay between cognitive processes and personality traits. While certain cognitive tasks, such as spatial processing and recognizing faces, are associated with increased activity in the right hemisphere of the brain, these tasks also involve the interplay of multiple areas and hemispheres of the brain. For example, recognizing faces involves not only visual processing in the right hemisphere but also language processing in the left hemisphere and emotional processing in the amygdala and other brain regions.
Despite the lack of scientific evidence supporting the idea of “left-brained” and “right-brained” individuals, the theory has remained popular in self-help literature and popular culture. Some people may find it helpful to identify with one side or the other to understand their strengths and weaknesses. Still, it’s important to remember that cognitive abilities and personality traits are complex and multifaceted and cannot be reduced to a simple dichotomy. Rather than focusing on the idea of “left-brained” or “right-brained” individuals, it may be more useful to focus on developing a wide range of cognitive and emotional skills and recognize that everyone has unique strengths and weaknesses.
How to Improve Brain Health
The brain is undoubtedly one of the most important organs in the body, responsible for controlling everything from movement and sensation to thought and emotion. Maintaining brain health is, therefore, essential for overall health and well-being, and there are several steps you can take to improve your brain health. Exercising regularly and eating a healthy diet rich in fruits, vegetables, whole grains, and lean proteins are important for brain health. Dehydration can impair cognitive function, so drinking plenty of water throughout the day is important. Similarly, sleep is essential for brain health, and lack of sleep can impair cognitive function and increase the risk of dementia. Social interaction has also been linked to improved cognitive function and a reduced risk of cognitive decline. Make time for social activities with friends and family and avoid unhealthy habits that may hamper or negatively alter the brain’s functioning. Smoking, excessive alcohol consumption, and drug use can all negatively affect brain health. Avoiding these habits can help protect your brain against cognitive decline. These basic lifestyle changes or adjustments can help maintain your brain health.
