Abstract: One aspect provides a method of treating a swallowing, mastication, or speech articulation disorder associated with a CNS lesion, PNS lesion, or lesioned brain region in a patient. The method includes: measuring a magnitude and a spatial extent of activation in a plurality of brain regions of the patient during movement of the tongue by functional magnetic resonance imaging (fMRI); generating a map of an individualized network of brain regions that control tongue movement; identifying at least one intact brain region functionally associated with the lesioned brain region based on the map of the individualized network of brain regions; tracking at least one tongue movement of the patient; providing neuronal feedback to the patient based on a level of activation of the at least one intact brain region identified and the at least one tongue movement; and instructing the patient to change at least one motor behavior of the tongue.
