"They're all going along the same corridors," said Stephen J. Morreale, Cornell University doctoral candidate in zoolog....... One problem with studying neural regeneration in vertebrate systems is that there are hundreds of thousands of neurons, making it impossible to identify what each individual cell does, she says. By contrast, the medicinal leech has 21 identical columns of neurons, called ganglia, which run up and down its bod...
