Abstract:
The role of the ipsilateral hemisphere in sensory functions remains unknown. The author describes 5 patients who presented with hemisensory symptoms due to unilateral strokes occurring in the left putamen, left thalamus, right putamen, right lateral medulla and left thalamic-internal capsular area, respectively. Sensory symptoms had gradually improved or remained stable after the initial events. However, when another stroke occurred on the contralateral thalamic-occipital, frontoparietal, lateral medulla, temporoparietal and pontine areas, respectively, previous sensory symptoms significantly worsened and became painful. These observations suggest that ipsilateral sensory pathways play a role in the modulation of sensory functions.
