Abstract This essay reviews the studies on cross-model reorganization of people with visual impairments in recent years. Researchers mainly discuss the following three aspects: (1) neural basis of cross-model reorganization of people with visual impairments; (2) effect of visual deficiencies in different stages on cerebral cross-model reorganization; (3) relationship between the complexity of task demands and cross-model reorganization of people with visual impairmens. These results provide valuable references for the advancement of neural healing physic and the reorganization of some deficiencies in pallium.
