Cortical electrical stimulation mapping was used to study neural substrates of the function of writing in the temporoparietal cortex. We identified the sites involved in oral language (sentence reading and naming) and writing from dictation, in order to spare these areas during removal of brain tumours in 30 patients (23 in the left, and 7 in the right hemisphere). Electrostimulation of the cortex...
Selective naming categories impairments for living and non-living things are widely reported in brain damaged patients. Electrostimulation mapping was used to study the possible anatomical segregation of living/non-living categories in a prospective series of patients operated on for tumor removal.Fifty brain mappings (patients with no language impairment; range: 14–80years; mean: 48years; 26 males;...
We have translated the most famous text of Sigmund Exner (1846–1926), which relates to the existence of a localised “writing centre” in the brain. We discuss its relevance to modern studies and understanding of writing and agraphia. In Exner’s most famous text, he hypothesised about the eponymous “Exner’s Area”, a discrete area within the brain that was located in the left middle frontal gyrus, which...
