Left-handed people have suffered a great deal of stigma over the years, but today all that has changed and experts have revealed details about their brains.
Being left-handed means having a predominant preference for use left hand instead of the right hand to perform tasks. This preference is reflected in a variety of daily activities, from writing and eating to throwing objects and using tools. Left-handedness manifests itself in approximately 10% of the world’s population and is a characteristic of laterality or manual dominance.
It is a complex phenomenon that involves a combination of genetic and neurological factors and although it was previously considered something bad or disrespectful, today it is known that it is a brain factor and it has nothing to do with a person’s education or manners.

What makes a person left-handed?
The tendency to be left-handed may have a hereditary componentIf one or both parents are left-handed, their children are more likely to be left-handed as well, although not necessarily.
In any case, it has not been proven that this is the reason 100% but it is one of the theories. Another of the reasons, the main theory covers which is the predominant side of the brain.
How the brains of left-handed people work
In left-handed people, brain dominance is often associated with the right hemisphere of the brain, which controls the left hand. In right-handed people, the left hemisphere of the brain, which controls the right hand, is generally dominant.
The way the brain organizes and distributes motor functions may differ in left-handed and right-handed people. Left-handed people may have a more symmetrical or less conventional brain organization compared to right-handed people.
Scientific studies have shown that the brain of a left-handed person can show greater plasticity, adapting differently compared to right-handed people.
