Hemianopia, Homonymous, Cortical Blindness, Unspecified Side of Brain
Ameliorating Stroke-induced Hemianopia Via Multisensory Training
This study seeks to determine the extent of the visual capabilities that can be restored in hemianopic stroke patients by a multisensory training technique and evaluate changes in the brain that the training induces.
