Restoring function after spinal cord injury, which damages the connections that carry messages from the brain to the body and back, depends on forming new connections between the surviving nerve cells. While there are some delicate surgical techniques that reconnect the nerves, researchers are also looking at ways to restore the connections themselves at a cellular level.

The progress a baby makes in the first year of life is amazing: a newborn can only wave its arms and legs about randomly, but not so long after the baby can reach out and pick up a crumb from the carpet. What happens in the nervous system that enables this change from random waving to finely coordinated movement? Scientists from the Max Planck Institute of Neurobiology in Martinsried near Munich, working with colleagues from New York and Philadelphia, have described a new type of nerve cell in mice which provides a valuable insight into this developmental phenomenon. During embryonic development, the projections from these cells grow from the spinal cord towards the brain. They may pave the way for other nerve cells which control voluntary movement and which only grow from the brain into the spinal cord after birth.
