Abstract
WHEN fibres in the central nervous system (CNS) of invertebrates and lower vertebrates are interrupted, regenerating axons grow beyond the lesion and form new synapses on denervated neurones. In the leech CNS, however, we have seen synapses formed by the regenerating fibres at the site of the lesion. The formation of synapses in regions where they are normally absent raises important questions about the manner in which axons grow to their targets and form orderly connections.
