Nonspiking and Spiking Local Interneurons in the Locust
Since the discovery of interneurons that normally do not produce action potentials (nonspiking interneurons) (for reviews, see Roberts and Bush, 1981), the question of why such neurons should exist has always been present. What advantages do they confer? Does their graded transmission of signals, an analogue process, offer greater flexibility than transmission effected by spikes, a digital process? Are these neurons specifically needed for local processing, because an individual neuron can perform many simultaneous but relatively independent computations at one time?
