11/11. Central pathway of taste: clinical and MRI study.We present 3 cases of hemiageusia due to focal ischemic lesions in the brainstem. Clinical presentation with discrete localization of these lesions suggests that the central taste pathway in humans projects ipsilaterally from the solitary nucleus up to the level of the upper pontine or lower midbrain before decussation. Associated partial sensory disturbance of the face or limb with lack of evidence of medial lemniscus decussation at the upper brainstem suggests that the medial lemniscus may not directly convey taste sensation.
