[Mechanism of the constant representation of the position of a sound signal source by the cricket cercal system neurons]. 1976

G I Rozhkova, and N A Polishcuk

Previously it has been shown that some abdominal giant neurones of the cricket have constant preffered directions of sound stimulation in relation not to the cerci (the organs bearing sound receptors) but to the insect body (fig. 1) [1]. Now it is found that the independence of directional sensitivity of giant neurones on the cerci position disappears after cutting all structures connecting the cerci to the body (except cercal nerves) (fig 2). Therefore the constancy of directional sensitivity of the giant nerones is provided by proprioceptive signals about cerci position.

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.

D002447	Celiac Plexus	A complex network of nerve fibers including sympathetic and parasympathetic efferents and visceral afferents. The celiac plexus is the largest of the autonomic plexuses and is located in the abdomen surrounding the celiac and superior mesenteric arteries.

D005725	Ganglia, Autonomic	Clusters of neurons and their processes in the autonomic nervous system. In the autonomic ganglia, the preganglionic fibers from the central nervous system synapse onto the neurons whose axons are the postganglionic fibers innervating target organs. The ganglia also contain intrinsic neurons and supporting cells and preganglionic fibers passing through to other ganglia.	Autonomic Ganglia,Ganglion, Autonomic,Autonomic Ganglion
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
