The frog dorsal root provides a useful model for the study of axonal regeneration in an adult vertebrate CNS. We have used the model to compare the regeneration of two very different types of axons within the same CNS environment and have found that regenerating dorsal root, as well as rerouted motoneuron axons, display similar growth patterns in the spinal cord. Both sensory and motor axons grow ...... hiện toàn bộ
