From One Crayfish to Another

study cultured stem cells from human embryos can proceed without violating the federal ban on embryo research in general. Since that decision, a great deal of excitement has arisen over the possibility that treatment of neurological disease may take a giant leap forward in the near future. The secrets to everything from preventing Alzheimer's Disease to reversing spinal cord damage may soon be unlocked by stem cell research, propelling us into an age of medicine where even hand transplants and cloning technology will join penicillin and pasteurization as commonplace. However, while only the most pessimistic scientist could deny the promise of stem cell research, it is still in the very early stages of development. Before we can realistically hope to treat many previously invincible neurological disorders, there is a great deal of work that still needs to be done. Neuroscience as a field must expand our knowledge of the brain and nervous system immensely in the coming years to facilitate the application of future discoveries.
