Lateralization of Brain Function: Understanding Hemisphere Dominance

Lateralization refers to the specialization of cerebral hemispheres for certain functions. In most right-handed people, the left hemisphere dominates language.

Left Hemisphere (Typically Dominant for Language)

• Logical, analytical thinking
• Mathematics, reasoning
• Reading, writing, speech production

Right Hemisphere

• Spatial perception
• Music perception
• Emotional processing
• Non-literal language (metaphors, humor)

Motor Control

Motor pathways are contralateral: left brain controls right body, right brain controls left body.
