Olfactory coding in Drosophila larvae investigated by cross-adaptation.
In order to reveal aspects of olfactory coding, the effects of sensory adaptation on the olfactory responses of first-instar Drosophila melanogaster larvae were tested. Larvae were pre-stimulated with a homologous series of acetic esters (C3-C9), and their responses to each of these odours were then measured. The overall patterns suggested that methyl acetate has no specific pathway but was det...
متن کاملModeling Peripheral Olfactory Coding in Drosophila Larvae
The Drosophila larva possesses just 21 unique and identifiable pairs of olfactory sensory neurons (OSNs), enabling investigation of the contribution of individual OSN classes to the peripheral olfactory code. We combined electrophysiological and computational modeling to explore the nature of the peripheral olfactory code in situ. We recorded firing responses of 19/21 OSNs to a panel of 19 odor...
متن کاملOlfactory responses of Drosophila larvae.
We studied complete dose-response curves for 53 odorants in the third instar larvae of Drosophila melanogaster. All odorants, except one, elicited an attraction response. Some odorants also elicited a decrease from their peak response at higher concentrations. This concentration-dependent decrease in olfactory response could be due to either desensitization or repulsion, 2 possibilities that we...
متن کاملInduction of Associative Olfactory Memory by Targeted Activation of Single Olfactory Neurons in Drosophila Larvae
It has been postulated that associative memory is formed by at least two sets of external stimuli, CS and US, that are transmitted to the memory centers by distinctive conversing pathways. However, whether associative memory can be induced by the activation of only the olfactory CS and a biogenic amine-mediated US pathways remains to be elucidated. In this study, we substituted the reward signa...
متن کاملComparison of Action Thresholds for Lepidopterous Larvae on Fresh- Market Cabbagel
A. M. SHELTON," M. K. SEARS,' J. A. WYMAN: AND T. C. QUICK4 ABSTRACT J. Econ.Entomol.76: 196-199 (1983) Five different action thresholds for control of Iepidopterous larvae on fresh-market cabbage were compared in Wisconsin and New York, and in Ontario, Canada, in 1981. An average of the three locations revealed that a threshold of one or more new feeding sites per head (Florida threshold) requ...
