Abstract : The consequences of inhibitory or excitatory interactions between pacemaker neurons were predicted mathematically and through digital-computer simulations, and were then confirmed experimentally in abdominal ganglia of Aplysia califor nica and in stretch receptors of Procambarus clarkii. Characteristic self-stablizing discharge patterns occur under conditions that do not involve feedback. Increased arrival rates of inhibitory (or excitatory) input can cause a paradoxical increase (or decrease) in firing rate. (Author)
