Final answer:
Lateralization refers to the specialization of function in each hemisphere of the brain, particularly with regard to language functions. Split brain research involves separating the hemispheres to study their individual functions.
Step-by-step explanation:
Lateralization refers to the specialization of function in each hemisphere of the brain. It mainly applies to differences in language functions, with the left hemisphere controlling the right side of the body and the right hemisphere controlling the left side of the body.
The concept of lateralization has been studied extensively through split-brain research, which involves separating the two hemispheres of the brain to treat epilepsy.
During this research, it was observed that split-brain patients have difficulty producing verbal responses based on sensory information processed on the right side of the cerebrum, suggesting that the left side is responsible for language function.
