Cortical and subcortical motor mapping
•
Stimulation mapping of cortical and subcortical
motor pathways enables the surgeon to identify
descending motor pathways during tumour removal.
•
New immediate postoperative motor deficits
documented in 59.3% of patients in whom a
subcortical motor tract was identified intra-
operatively and in 10.9% of those in whom sub-
cortical tracts were not observed.
•
Permanent deficits observed in 6.5 and 3.5%,
respectively
