Sounds like a possibility. The problem here is of course getting the cells connected into the network. What usually happens when young nerve cells are transplanted (when things go right :-) is that they start sending out axons to connect to neighboring or more remote cells, depending on chemical signatures and their own preferences. It is not obvious that transplants will help, but some experiments on rats have been quite encouraging.
