Abstract
APPLYING a weak electric current to the cerebral cortex of awake neurosurgical patients is an established method for mapping language zones on the basis of stimulation-evoked errors. Two new findings are reported here—the topographical extent of language cortex in an individual subject can be wider than that proposed in the classic maps, and, within this zone different sites are variably committed to language as measured by the naming function.
