Kortikale und subkortikale Organisation des Schluckvorgangs

Because no detailed information exists regarding the topographic representation of swallowing musculature on the human cerebral cortex in health or disease, different functional imaging methods are used to study the cortical topography of human oral, pharyngeal and esophageal musculature in healthy individuals and in patients. The findings demonstrate that swallowing musculature is discretely and somatotopically represented on the motor and premotor cortex of both hemispheres but displays interhemispheric asymmetry, independent of handedness. Following stroke, dysphagia appeared to be associated with smaller pha…
