Scholarcy highlights
- Recent data indicate that dysphagia may occur following unilateral cortical stroke; the elucidation of specific cytoarchitectonic sites that produce deglutition disorders remains unclear
- As confirmed by videofluoroscopy, was evident in 3 of the 4 patients; all had lesions that involved the anterior insula, whereas the only patient without dysphagia had a lesion restricted to the posterior insula
- These data suggest that the anterior insula may be an important cortical substrate in swallowing
- Discrete lesions of the anterior insula may disrupt these connections and, thereby, produce dysphagia
