Left Brain VS Right Brain – Dominance & Differences – Tips, News and Experiences 2024

The human brain is a remarkably intricate and fascinating organ that regulates and harmonizes all bodily functions. It plays a crucial role in our daily life, from sensing and perceiving to thinking and feeling. The concept of left-brain and right-brain dominance is a widespread belief that proposes that the two hemispheres of the brain have unique and distinct functions.

However, recent studies have revealed that this notion is largely inaccurate, and the brain is much more intricate and interconnected than we previously understood. This article aims to explore the true nature of the human brain, its mechanisms, and debunk the myth of left and right brain dominance. Additionally, we will provide valuable insights and supplements for enhancing and sustaining brain health.

We invite you to join us in unraveling the mysteries of the human brain and understanding its complexity. By doing so, we can ensure that we are taking the best possible care of this vital organ that shapes our lives.

Right Brain, Left Brain Myths

The widely popular theory of left and right brain dominance is actually a myth. In the 1960s, research initially suggested that the two sides of the brain had distinct functions, but we now understand that the brain is much more complex and interconnected than previously thought. Brain activities involve coordination between both the left and right hemispheres, and there is no concrete evidence supporting the idea of left-brain or right-brain dominance.

However, some tasks are unevenly shared between the two brain hemispheres. Recently, there has been an increase in the prevalence of “neuromyths,” which are false beliefs about the brain. Many of these myths have been developed as learning theories or methods, and they often stem from scientific research.

This makes it challenging to distinguish between what is true and what is not. To avoid educational dead ends, it is essential to disprove these myths since they are incomplete, extrapolated beyond the facts, or entirely untrue. Here are some examples of neuromyths that have gained popularity:

  • “I’m a left-brain person, and she’s a right-brain person.”
  • “But I read somewhere that we only use 10% of our brain anyway.”
  • “Learn while you sleep!”

Left Brain

According to the left brain hypothesis, the left hemisphere of the brain is responsible for processing information. It handles language processing, logical thinking, math and science, planning and organization, critical thinking, problem-solving, working with numbers, and setting and achieving goals. Additionally, left-brained individuals tend to be right-handed.

However, this notion is an oversimplification of a complex process. Most functions are the result of collaboration between multiple regions of the brain. The idea that the left and right sides of the brain have distinct functions is mostly untrue. Instead, both hemispheres of the brain work together and overlap in performing various tasks. Furthermore, the brain has a high level of adaptability, and different brain areas can take over the roles of damaged or removed areas.

Right Brain

The right-brain hypothesis suggests that the brain’s right hemisphere controls various functions, including spatial awareness, facial recognition, creativity, and self-expression. Right-brained people are said to be better at understanding and navigating the environment, recognizing familiar objects and people, generating new ideas and concepts, and appreciating and creating music and art. The theory suggests that left-handed people are right-brained. Also, some studies support the right-hemisphere dominance paradigm for all emotions.

How Does The Brain Work Actually?

The human brain is the most complex organ in the body, responsible for controlling and coordinating all bodily functions. Our understanding of the brain is constantly evolving due to ongoing research, and it’s important to stay open-minded and rely on reputable sources for up-to-date information. One common belief about the brain is that the left and right hemispheres have distinct functions, with the left side being more logical and the right side more creative.

However, recent research shows that this belief is largely untrue. While the two hemispheres do have different functions, they work together to complete all tasks, and they are interconnected rather than separate. The brain is responsible for many functions, including sensation, perception, cognition, and emotion. It is also capable of adapting to damage or changes by rewiring itself to compensate for lost functions.

Measuring Of The Dominance Of Right VS Left Brain

As previously mentioned, the concept of left-brain or right-brain dominance is not scientifically valid. Studies have shown that most individuals use both sides of the brain equally, and the theory that the dominant hand or eye is related to the brain’s hemispheres is largely untrue. Determining a person’s dominant hemisphere is not possible through conclusive methods.

While brain scans and psychological tests can provide information about the brain’s structure and functionality, they are considered inconclusive and should not be used to make definitive statements about a person’s brain function.

It’s important to remember that the brain is highly adaptable, and different brain regions can take over the roles of damaged or removed areas. The idea of left-brain or right-brain dominance is an oversimplification of a complex phenomenon, and it’s essential to consult reputable sources for the most up-to-date information about brain research.

Supplements For Better Brain Performance

Recent studies have shown that more than 25 percent of individuals above the age of 50 take brain health supplements with claims of improving memory, attention, and focus. However, there is no substantial evidence to prove their effectiveness. Instead, a diet rich in vitamins and minerals, such as the DASH or Mediterranean diet, can improve overall health and brain function.


CBD (Cannabidiol) is a compound found in hemp and marijuana plants. It has potential benefits for brain health, including reducing inflammation and promoting neuroplasticity. Some studies suggest that CBD may help treat anxiety, depression, and PTSD, but more research is needed to fully understand its effects on the brain and its potential as a brain health supplement. CBD is a non-psychoactive compound, meaning it will not get you high, and it is legal in most places.

However, it’s important to check the laws in your country and state before consuming it. While these substances may be helpful for brain health, there is still a lack of solid evidence proving their benefits for otherwise healthy individuals. It’s important to remember that supplements should not replace a healthy diet and lifestyle, and it’s always best to consult a healthcare professional before adding supplements to your routine.
