The neurosurgeon directly delivers an electric current onto the brain parenchyma with small electrodes in order to precisely locate functional areas that must be avoided during surgery. He looks for language interferences induced by stimulation whilst the patient is asked to perform linguistic tasks ( e.g., picture naming). In the field of neurosurgical oncology, refinement of neurosurgical technique and routine use of stimulation mapping has enabled safer operations with better outcomes. In the field of neuroscience, ESM studies, in which naming, reading and writing tasks have been used, have enabled a better understanding of language functional organization in the brain. The anatomical correlates of specific language-processing components (phonology, semantics, and articulatory networks) have been identified in the perisylvian region. In addition, ESM specified the dissociation of phonologic representations transcoded from either alphabetic or numeric Arabic formats of numbers in the supramarginal gyrus. ESM also revealed a frontal bridging area between orthography and motor programs specific to handwriting located in BA6.
