[Modification of bioelectric functions in the nervous system as a result of neurotoxin action].

Natural neurotoxins are promising molecules in the actual search for the development of alternative pest management since chemical insecticides pose unacceptable risks to the environment and to health. The aim of the article is to describe the application of two electrophysiological methods (double-oil-gap technique used on cockroach isolated giant axon and microelectrode technique used on cockroach neurosecretory DUM cells in situ) to study neurotoxin effects on insect nervous system function.
