The brain is divided into two hemispheres, the left and the right. Each hemisphere has different functions, with the left hemisphere being responsible for language and logical thinking, while the right hemisphere is more involved in spatial awareness and creativity.
The brain's control over the body is crossed, meaning that the left hemisphere controls the right side of the body, and vice versa. This phenomenon is known as contralateral control. Therefore, if an individual has left cerebral dominance, meaning their left hemisphere is more dominant, it would result in greater control and coordination of the right side of the body.
Handedness is determined by a combination of genetic and environmental factors. While the exact cause of handedness is not fully understood, studies suggest that it is influenced by a combination of genes, prenatal hormones, and brain development.
Given that the left hemisphere is involved in language and logical processing, it is thought to play a crucial role in the development of right-handedness. Studies have shown that the left hemisphere tends to be larger and more active in individuals who are right-handed, while left-handed individuals may have a more balanced or even a right hemisphere dominance.
However, it is important to note that not all individuals with left cerebral dominance are right-handed, and not all right-handed individuals have left cerebral dominance. Handedness and cerebral dominance can vary from person to person, and there can be individuals who are left-handed with left cerebral dominance or right-handed with right cerebral dominance, although they are rarer.
