Document Summary
Neuroscience: the study of the brain and nervous system. Telomeres: a a part of the chromes that prevents genes from degrading or recombining with our genetic material. Telomeres get smaller and smaller with each cell replication, until eventually they are gone and the cell stops replicating and dies; when large numbers of cells stop replicating we age. It is believed by some that if we could protect the telomeres, our cells could replicate inde nitely. Brain and head transplants have worked with animals with nominal degrees of success but has never been attempted on humans. Several decades ago, scientists relied one one of the following methods: Examining autopsy tissue: allows neuroscientists to see what our brains lok like, but has the obvious drawback of telling them little about how these systems worked when the person was alive and using them. Testing the behavior of patients with damage to certain parts of the brain:
