Abstract

Several classes of motor neurons within the stomatogastric ganglion of the spiny lobster Panulirus interruptats participate in the generation of the pyloric rhythm. Graded synaptic transmission among these motor neurons is an essential component in the production of the triphasic pyloric motor pattern1. Previous work characterized graded synaptic transmission2, but in a “static context” where the time dependent dynamics were ignored.
