Final answer:
The left hemisphere is more involved in language functions, while the right hemisphere is more involved in abstract reasoning and visual-spatial abilities. Each hemisphere controls the opposite side of the body. Research on hemispheric dominance and behavior is inconsistent.
Step-by-step explanation:
The left and right cerebral hemispheres have some differences in their functions and connections to the body. In most people, language functions are more concentrated in the left hemisphere, while abstract reasoning and visual-spatial abilities are more concentrated in the right hemisphere. Each hemisphere of the brain interacts primarily with the opposite side of the body, meaning that the left hemisphere controls the right side of the body and the right hemisphere controls the left side of the body.
Research on hemispheric dominance and specific behaviors has produced inconsistent results, so it is better to think of how the two hemispheres interact rather than attributing certain behaviors to one hemisphere over the other.
