Abstract: With the increasing morbidity of brain injury suffered from different causes,a large number of researchers focus on the recovery of the post-brain-injury.Based on the brain plasticity theory,this paper reviewed some possible recovery mechanisms of the post-brain-injury,including changes in neural cells,functional reorganization,functional compensation,changes in the excitability of cortex,and specific skills learning.

Key words: brain injury, brain plasticity, functional reorganization, synaptic plasticity, functional training, review
