Which hand to useIs it a choice given to people or is it a game our brains play with us?

Actually be right and left handed It would not be right to attribute this to one reason; there are many reasons. Let us look together.

Which hand we use often has to do with genetics.

Although it was previously thought that a single gene caused this condition, new research has shown that this trait is He suggests that it may be under the influence of as many as 40 different genes. Although each of these genes individually has a weak effect, together they play an important role in determining handedness.

Genetic studies have revealed microtubule-associated genes (TUBB, MAP2 and MAP) and left-handedness. In this case, we can easily argue that genetics plays a role, even if it is a small one.

Does which brain we use in this case also have an influence?

The brain consists of two areas: right and left. The brain has a cross-connection structure, which means that the movements of the left side of the body are controlled by the right hemisphere, and the movements of the right side are controlled by the left hemisphere. Your left side is more logical and your right side is more emotional. And we have heard that he is creative. This situation, which we have heard for years, also concerns our hand preference.

Because in the brain structures of left-handers This asymmetry is believed to contribute to left-handedness.

Most biological molecules have chemical asymmetry.

Most DNA exists as a right-handed double helix. This asymmetry at the cellular level exhibits behaviors such as clockwise cell rotation during embryonic development and provides a certain order in the formation of organs. This asymmetry is caused by genetic and epigenetic factors. It is regulated and can also affect the asymmetry of organs such as the brain.

This is the situation that places us right handed or left handed It’s enough to do it.

There is also an environmental factor.

Left-handedness or right-handednessis not limited to genetic factors alone. Environmental factors and cultural pressures in the womb can also influence this choice. There is a general “never be left-handed!” Because the situation is dominant, the person’s choice can be shaped in this way, albeit with little influence at a young age.
