eloquent brain areas
Pronunciation: EL-oh-kwent
Brain regions where damage would result in significant neurological deficit, requiring special surgical consideration.
Full Definition
Eloquent brain areas are regions of the brain where surgical damage would result in permanent and significant neurological deficits that would substantially impact quality of life. These areas include the motor cortex, sensory cortex, language areas (Broca's and Wernicke's areas), visual cortex, brainstem, and deep nuclei. Surgical planning in eloquent areas requires specialized techniques such as awake craniotomy, cortical mapping, and intraoperative neurophysiological monitoring to preserve neurological function while achieving tumor resection.
Usage
Usage note: Use 'eloquent brain areas' for broader regions; 'eloquent cortex' refers specifically to cortical areas.
In Context
- "The tumor's proximity to eloquent brain areas necessitated awake surgery with cortical mapping." — Preoperative planning note
- "Resection was limited to preserve eloquent brain areas controlling speech and motor function." — Operative report
