Studying the linkages among the brains billions of nerve cells is a bit like maneuvering through a dense thicket while trying not to break any branches. Tangled cellular appendages, called axons and dendrites, form a virtually impenetrable network for anyone who wants to observe nerve-to-nerve connections intact.
Nevertheless, two groups of neurobiologists are making headway. By using a nerve-muscle junction as a surrogate, one team has demonstrated how permanent changes...
