摘      要：Injuries to spinal motoneurons manifest in a variety of forms,including damage to peripheral axons,neurodegenerative disease,or direct insult *** injuries produce a variety of negative structural and functional changes in both the directly affected and neighboring *** is a relatively simple behavioral intervention that has been demonstrated to protect against,and accelerate recovery from,these negative *** this article,we describe how exercise is neuroprotective for motoneurons,accelerating axon regeneration following axotomy and attenuating dendritic atrophy following the death of neighboring *** both of these injury models,the positive effects of exercise have been found to be dependent on gonadal hormone *** we describe a model in which exercise,hormones,and brain-derived neurotrophic factor might all interact to produce neuroprotective effects on motoneuron structure following neural injury.
