The occurrence of neuronal death during development is well documented for some neuronal populations, such as motoneurones and dorsal root ganglion cells, whose connecting pathways are clearly defined. Cell survival is thought to be regulated largely by target and input connections, a process that serves to match the size of synaptically linked neuronal populations. Far less is known about interneurones. It is assumed that most interneurone populations are excluded from this process because their connections are more diffuse. Recent studies on the rat spinal cord have indicated that interneurone death does occur, both naturally during development and induced following peripheral nerve injury. Here the evidence for spinal interneurone death is reviewed and the factors influencing it are discussed. There are many functional types of interneurones in the spinal cord that may differ in vulnerability to cell death, but it is concluded that for most spinal interneurones the traditional view of target regulation is unlikely. Instead it is proposed that developmental interneurone death in the spinal cord forms part of a plastic response to altered sensory activation rather than a size-matching exercise. There is also emerging evidence that interneurone death may play a more direct role in some neurodegenerative diseases than hitherto considered.
