A central pattern generator (CPG) is defined as a set of neurons whose members work together to generate organized motor output activity. A round-table discussion on central pattern generators was held on November 21, 2012 as part of the Fifth All-Russian Conference on Animal Behavior in Moscow. The main topics of discussion were: 1) the mechanisms of the(More)
Behavioral choice is known to depend on context, i.e., a variety of internal and external factors: previous experience, behavioral state, presence of food, etc. How is the totality of factors determining behavioral choice translated at the cellular level? This review presents neuroethological data providing evidence that context is expressed at the(More)
Previous studies have shown that nitric oxide (NO) transforms the responses of various neurons to glutamate, though it remained unclear whether this mechanism is involved in the formation of behavior. We therefore studied the buccal generator of the feeding rhythm of the mollusk Lymnaea stagnalis (pond snail). In this organism, glutamate and NO are(More)
The mechanisms of the effects of some types of behavior on others have received little study. The present investigation addresses the phenomenon present in male crickets of the species Gryllus bimaculatus, consisting of the powerful activation by transient flight (3 min) of aggression to another male and of the female courtship program. We found that flight(More)
Experiments on the models of epileptiform seizure and hemorrhagic stroke (Krushinskii–Molodkina rats) showed that selective inhibitors of inducible and neuronal NO synthases (aminoguanidine and 7-nitroindazole) significantly decrease the mortality rate, reduce the severity of motor disorders, and prevent the development of intracranial hemorrhages under(More)
Previous studies have shown that one version of the coordination of the central buccal generator in the mollusk Lymnaea stagnalis with the rhythm of neuron B2, which controls esophageal motility, is associated with the occurrence of giant hyperpolarization waves on B2 neurons. The present report describes new neurons which appear to be the source of these(More)
