lateralization
This term describes the asymmetrical distribution of functions across two halves of a system, most commonly applied to the brain or biological motor skills. It carries a clinical and scientific connotation, focusing on the efficiency gained when specific tasks are delegated to a specialized side rather than being processed uniformly.
In a neurological context, it refers to the division of labor between the left and right hemispheres. In a behavioral context, it describes the physical manifestation of this specialization, such as handedness or eye dominance. Because it describes a biological process or state, it is treated as an uncountable mass noun in most scientific discussions, referring to the general phenomenon rather than individual instances.
Meanings
The functional specialization of the two hemispheres of the brain, where certain cognitive processes are predominantly handled by one side.\n\nResearch into cerebral lateralization suggests that language processing is typically concentrated in the left hemisphere for most right-handed individuals.
