Abstract:
:We have recently examined the electrophysiology and ultrastructure of approximately 100 tactile spines from the metathoracic legs of adult cockroaches. In only one animal the single sensory neuron that innervates the spine was replaced with a pair of apparently identical neurons which we believe were both functional. As far as we are aware this is the first reported study of unprovoked duplication in a peripherally-located insect sensory neuron.
