Scientists Discover How Nerve Cells Move From Target To Target As They Wire Up The Developing Embryo

Summary:
Scientists at the University of California, San Francisco have discovered how an advancing axon is able to turn away from an attractive target almost as soon it is reached. The strategy allows the pioneering nerve to continue on its journey even though the attractive site continues sending signals to stay. The behavior prevents pioneering nerves from backtracking and laying down faulty wiring that could spell disability or death to the embryo.

Like a restless Romeo forever seeking the perfect embrace, a developing nerve cell reaches its final destination in the brain by drawing close to one target, then turning to a series of newer attractions as it continues on a halting course toward a predestined rendezvous with another nerve cell.
