Neural Transmission in Invertebrates

Abstract

"The purpose of this review is to try to "take stock" of the approaches and advances that have been made towards the problem of the functioning of central nervous systems especially in invertebrates. Its main stress will be on theoretical aspects, and on discussion of the more obvious deficiencies in facts, which prevent the attainment of the goal; discovering how the actions of the effectors are correlated with the sensory stimuli." Discussion covers the nerve impulse, transmission between nervous elements other than by synapses, types of synaptic transmission shown by giant fiber systems (2-way synapses; relay, integrative, and multiplying 1-way synapses), synaptic connections not involving giant fibers, spontaneous activity, nerve nets, neuromuscular transmission in Crustacea, insecta, and other groups.
