Tongues of patients after partial glossectomy due to carcinoma and those of healthy controls were electrically stimulated on both sides below the pain threshold. BOLD magnetic resonance responses were then recorded. In healthy individuals bilateral signals in the expected cortical regions were registered, whereas patients after partial glossectomy only showed a response in the right cortical hemisphere corresponding to their handedness. These signals were weaker and compared to the healthy individuals localised more medially. The data suggest a cortical reorganisation, neuronal change and unmasking of existing nerval connections after partial glossectomy.
