cortical mapping

Establishing the relationship between various structures of the brain and their functions. It is a technique used in neurosurgery to determine which parts of a diseased brain may be safely excised. Maps made of eloquent brain structures help surgeons minimize the damage they do when they remove tumors or seizure foci.

For cortical mapping to represent Hangul (PhonoS) versus Hanja (LogoS) in the subjects with the first language (L1) PhonoS divided into two groups as high versus low competency to L2 LogoS (High-C versus Low-C), Low-C group demonstrated activation and lateralization in the right SPL and VLPFC as well as left SMA, likely due to neural efficiency such as visuospatial attention and cognition rather than core neurolinguistic neural demand like OrthoR processing.
Surgical therapy for central area status requires cortical mapping to identify sensorimotor cortex, prevent postsurgical paresis, and maximize the size of excision.
Intra-operative cortical mapping (TOM), although invasive, can greatly aid the surgeon's ability to remove mass lesions in proximity to eloquent areas.
