[Optimal air flow directions for activating the giant neurons of the cercal system in the cricket, Gryllus domesticus]. 1978

G I Rozhkova, and N A Polishchuk

Studies have been made of the directional sensitivity of the giant neurons in the abdominal nervous chain of the cricket during the effect of air flows and sound stimuli on the cercal system. It was found that the axis of sonic and air flow diagrams of the directional sensitivity for a given neuron are practically identical. On the basis of flow diagrams, in each of the connectives at the edge of terminal abdominal ganglion 4 giant neurons were identified which may form a system accounting for the reception of air flows of any directions approximating horizontal plane. It was found that 3 neurons from this system receive the main bulk of excitatory impulsation from the ipsilateral cercus, and only 1 of them--from the contralateral one. The data obtained are discussed in relation to morphological and physiological characteristics of the investigated group of giant neurons.

UI	MeSH Term	Description	Entries
D007313	Insecta	Members of the phylum ARTHROPODA composed or organisms characterized by division into three parts: head, thorax, and abdomen. They are the dominant group of animals on earth with several hundred thousand different kinds. Three orders, HEMIPTERA; DIPTERA; and SIPHONAPTERA; are of medical interest in that they cause disease in humans and animals.
