functional mapping
Intraoperative techniques used to identify and preserve critical brain functions during neurosurgical procedures.
Full Definition
Functional mapping encompasses various intraoperative techniques used to identify and preserve critical brain functions during tumor resection in eloquent brain areas. These techniques include direct electrical stimulation, awake craniotomy with language testing, and real-time neurophysiological monitoring. The goal is to maximize tumor resection while preserving neurological function, particularly in areas responsible for motor, sensory, language, or cognitive functions. Functional mapping allows surgeons to establish safe resection margins and avoid permanent neurological deficits by providing real-time feedback about the functional significance of brain tissue.
