lateralization
Noun: The process or state in which specific cognitive functions or neural processes become predominantly localized or specialized in one hemisphere (side) of the brain, typically the left or right.
This term is used primarily in neuroscience, psychology, and medicine to describe the asymmetric distribution of functions in the brain. It refers to the phenomenon where certain tasks, such as language or spatial reasoning, are mainly controlled by one side of the brain.
- Noun:
- The lateralization of language to the left hemisphere is common in most right-handed individuals.
- Researchers study the degree of lateralization for facial recognition in the brain.
- Atypical lateralization may be observed in some neurological conditions.
"Hemispheric lateralization": A more specific term emphasizing the specialization of the left and right cerebral hemispheres.
- The course focused on theories of hemispheric lateralization.
"Functional lateralization": Highlights that the specialization pertains to specific brain functions.
- The fMRI scan provided clear evidence of functional lateralization for the task.
Lateralize (verb): To cause or undergo the process of becoming lateralized.
- Language functions tend to lateralize early in development.
Lateralized (adjective): Describing a function that is specialized to one hemisphere.
- The patient showed a strongly lateralized response to the auditory stimulus.
- Hemispheric specialization
- Hemispheric dominance (though this can imply a stronger hierarchy)
- Functional asymmetry (in the brain)
- Brain asymmetry: A broader term referring to structural or functional differences between the brain's hemispheres, of which lateralization is a key aspect.
- Contralateral control: The principle that one hemisphere of the brain controls the opposite side of the body, a concept closely related to understanding lateralized functions.
-
localization of function on either the right or left sides of the brain
