Representation of pheromones, interspecific signals, and plant odors in higher olfactory centers; mapping physiologically identified antennal-lobe projection neurons in the male heliothine moth
The arrangement of anatomically separated systems for information about general and pheromone odorants is well documented at the initial levels of the olfactory pathway both in vertebrates and insects. In the primary olfactory center of the moth brain, for example, a few enlarged glomeruli situated dorsally, at the entrance of the antennal nerve, are devoted to information about female-produced...
متن کاملIntegration of the Antennal Lobe Glomeruli and Three Projection Neurons in the Standard Brain Atlas of the Moth Heliothis Virescens
Digital three dimensional standard brain atlases (SBAs) are valuable tools for integrating neuroimaging data of different preparations. In insects, SBAs of five species are available, including the atlas of the female Heliothis virescens moth brain. Like for the other species, the antennal lobes (ALs) of the moth brain atlas were integrated as one material identity without internal structures. ...
متن کاملRepresentation of primary plant odorants in the antennal lobe of the moth Heliothis virescens using calcium imaging.
The primary olfactory centre, the antennal lobe of Heliothis virescens moths, contains 62 glomeruli which process plant odour information and four male-specific glomeruli which form the macroglomerular complex, involved in processing information about pheromone and interspecific signals. Using calcium imaging, we recorded the spatio-temporal activity pattern of the glomeruli in the anterior ant...
متن کاملA multisensory centrifugal neuron in the olfactory pathway of heliothine moths.
We have characterized, by intracellular recording and staining, a unique type of centrifugal neuron in the brain olfactory center of two heliothine moth species; one in Heliothis virescens and one in Helicoverpa armigera. This unilateral neuron, which is not previously described in any moth, has fine processes in the dorsomedial region of the protocerebrum and extensive neuronal branches with b...
متن کاملA Specific Male Olfactory Sensillum Detects Behaviorally Antagonistic Hairpencil Odorants
Within insect species, olfactory signals play a vital role in communication, particularly in the context of mating. During courtship, males of many moth species release pheromones that function as aphrodisiacs for conspecific females, or repellants to competing conspecific males. The physiology and antennal lobe projections are described of olfactory receptor neurons within an antennal sensillu...
