[The extracardiac regulation of the work of the heart in the American cockroach].
Some features of extracardiac regulation of the cockroach heart activity have been studied. Analysis of electrocardiogram characteristics when cutting and irritating the different nervous elements showed that the vegetative (stomatogastric) nervous system could evoke the increase of the heartbeat amplitude. Both excitatory and inhibiting influences can be sent to the heart by segmental nerves, these influences being eliminated by dissociation of connections between the head and thoracic ganglia. Possible mechanisms of the somatic and vegetative components integration of insect behavioural reactions are discussed.
