Magnetic resonance imaging of 1,000 people revealed that the human brain doesn't actually favor one side over the other. The networks on one side aren't generally stronger than the networks on the other side.
Because the left hemisphere also controls the dominant right hand, it came to be widely regarded as the dominant or major hemisphere, and the right as nondominant or minor.
Their brain test project showed: 41% of earch-dwellers are left-brained, while only 27% are right-brained. In 32% of participants, the two hemispheres exert equal influence on thinking. (Source: Sommer+Sommer, n=35.345. 657 people from 205 countries.)
Scientists deduced that the left brain was better at language and rhythm, while the right brain was better at emotions and melody. However, this doesn't mean that the two halves are entirely separate. The myth of the totally opposite hemispheres persists for a variety of reasons. It satisfies the need for order.
Ninety-five percent of the human population is left-brain dominant, and those people tend to be right-handed. The dominant side of your brain is where your speech and language center is located.
October 6, 2013. The left and right hemispheres of Albert Einstein's brain were unusually well connected to each other and this may have contributed to his brilliance, according to a new study [1], the first to detail Einstein's corpus callosum.
Traditionally, the majority of entrepreneurs have been logical thinkers, problem solvers, and pay attention to details. These are the stereotypical left-brain engineers.
In a 2013 research review , they found no proof that this theory is correct. Magnetic resonance imaging of 1,000 people revealed that the human brain doesn't actually favor one side over the other. The networks on one side aren't generally stronger than the networks on the other side.
What are "left-brained" people like? They are described as logical, analytical, and orderly. The theory suggests that people who are left-brain dominant do well in careers that involve linear thinking, math, and verbal information, such as an accountant, scientist, or computer programmer.
Among the famous people in history, Rabindranath Tagore was a right-brainer, Albert Einstein was a left-brainer, while Leonardo da Vinci was probably more balanced.
While everyone uses both sides of their brains in work (and in life), people who think of themselves as right-brained tend to be creative, emotional, and intuitive. They are more likely an imaginative and innovative thinker and are often drawn to fields where they can express themselves freely and help others.
But this does not justify the pop psychology concept of “left-brained” or “right-brained.” The two hemispheres are different, yet brain imaging technologies like functional magnetic resonance imaging (fMRI) suggest that, on average, we use both sides of our brain equally. We are all “brain-ambidextrous.”
Right-brainers can be disorganised, unpredictable and more often than not, very good with people. They are spontaneous, creative and more emotional than left-brainers, often pondering and acting on their feelings. They are intuitive, good at problem solving and more comfortable with the unknown.
“Located in the left side of our brain is the masculine force. It is the part of us that is assertive, logical, analytical, doing, controlling, aggressive, striving, projecting, hard, organizing, rushing, thrusting, always pushing us to survive, and has its origin in our minds.
Thus, physical evidence has revealed that the right hemisphere, while indeed the brain's more "emotional" side, is not solely responsible for processing the expression of emotions.
The neural system for emotions linked to approaching and engaging with the world – like happiness, pride and anger – lives in the left side of the brain, while emotions associated with avoidance – like disgust and fear – are housed in the right. But those studies were done almost exclusively on right-handed people.
You may find that your left-brain weak child has problems with memorizing lists or tables, has difficulty understanding verbal instructions, struggles with writing, cannot focus on one task for too long, and generally doesn't enjoy school.
The idea that left-handed people are more intelligent than right-handers is a myth. There have been lefty geniuses in history like Leonardo da Vinci, but this is not part of a larger pattern. If anything, the opposite is true.
Children who have stronger left-brain functions tend to be more analytical in their thinking and typically perform well academically. They may have a great ability to memorize large amounts of data, have a large vocabulary, and are detail-oriented.
In test taking, the left brainer prefers the black-and-white choices presented in multiple choice questions while the right brainer may prefer essay questions where the whole picture can be given. 80% of the struggling learners that I see are right brain dominant.
Frontal cortex
Geniuses have a denser concentration of mini-columns than the rest of the population – it seems that they simply pack more in. Mini-columns are sometimes described as the brain's 'microprocessors', powering the thought process of the brain.
According to Sara Mahuron of Chron.com, left-brained people could pursue careers as lawyers, civil engineers, scientists, computer programmers and accountants. “Lawyers represent clients in court, prepare legal documents, interpret laws and regulations and analyse cases.
