left hemisphere dominance

Left hemisphere dominance refers to the idea that certain skills—like language, logical reasoning, and analytical thinking—are primarily processed in the left side of the brain. While both hemispheres work together, the left side tends to handle tasks involving speech, reading, writing, and mathematical calculations. This dominance is not absolute; many functions involve cooperation between both sides. Understanding this helps us appreciate how different brain regions contribute to our abilities and how brain injuries can affect specific skills depending on which side is impacted.
