brodmann's area
Definition
Noun: - A region of the cerebral cortex defined by its cellular structure: "Brodmann's area" refers to any of the specific regions of the brain's outer layer (the cerebral cortex) that were mapped and numbered by the German anatomist Korbinian Brodmann based on the distinct organization, type, and density of its cells (cytoarchitecture).
Usage
- This term is used exclusively in the fields of neuroscience, neurology, and anatomy to precisely identify and discuss functional regions of the brain.
- It is typically used with a number (e.g., Brodmann area 4, Brodmann's area 17) to specify a particular cortical region.
Examples
Advanced Usage
- Used as a standard reference: The Brodmann map, though over a century old, remains a fundamental reference system for correlating brain structure with function in modern neuroimaging studies.
- Context of discussion: The term is almost always used in technical, academic, or clinical contexts. It is not used in everyday conversation.
Variants and Related Words
- Brodmann area: A common variant where the possessive 's' is omitted (e.g., "Brodmann area 10").
- Cytoarchitectonic area: A more general term for a cortical region defined by its cellular makeup.
- Cortical area: A broad term for any region of the cerebral cortex.
Synonyms
- Cytoarchitectonic field: A direct synonym emphasizing the structural definition.
- Cortical region (specified by number): A functional synonym when the Brodmann number is provided (e.g., "the cortical region identified as area 41").
Notes on Meaning
- The term has only one specific, technical meaning related to brain mapping. It does not have idiomatic uses, phrasal verbs, or different common meanings.
Noun
-
one of the cortical areas mapped out on the basis of its cytoarchitecture
