localization principle
Definition
Noun: 1. Localization of function; localisation of function; localization principle; localisation principle; localization; localisation: (physiology) the principle that specific functions have relatively circumscribed locations in some particular part or organ of the body. This is a fundamental concept in neuroscience and physiology stating that distinct brain regions or bodily organs are responsible for specific tasks, such as speech, movement, or vision.
Usage Examples
- Noun:
- The localization principle is a key concept in understanding how brain injuries affect specific abilities.
- Modern neuroscience has refined, but not completely overturned, the classical localization principle for many cognitive functions.
- The experiment's results provided strong evidence in support of the localization principle for sensory processing.
Advanced Usage
- "Challenges to strict localization": Refers to the modern understanding that while core functions are localized, complex cognition involves distributed networks across the brain.
- Contemporary research acknowledges the localization principle but emphasizes the importance of neural plasticity and interconnected networks.
Variants and Related Words
- Localize (verb): To assign or discover the specific location of something, especially a function within the body.
- Scientists tried to localize the brain activity associated with decision-making.
- Localized (adjective): Restricted to a specific place or part.
- The patient had a localized pain in the lower back.
Synonyms
- Localization of function
- Functional specialization
- Cortical localization (when specifically referring to the brain's cortex)
Related Concepts (Not Phrasal Verbs or Idioms)
- Phrenology: A now-discredited theory that attempted to apply an extreme form of the localization principle by mapping mental faculties to bumps on the skull.
- Brain mapping: The modern scientific practice of correlating brain structure and function, which operates on the general premise of the localization principle.
- Aphasia: A language disorder often caused by damage to specific, localized brain areas (e.g., Broca's area, Wernicke's area), providing clinical evidence for the principle.
Noun
-
(physiology) the principle that specific functions have relatively circumscribed locations in some particular part or organ of the body
