Quantum origins of molecular recognition and olfaction in Drosophila.
The standard model for molecular recognition of an odorant is that receptor sites discriminate by molecular geometry as evidenced that two chiral molecules may smell very differently. However, recent studies of isotopically labeled olfactants indicate that there may be a molecular vibration-sensing component to olfactory reception, specifically in the spectral region around 2300 cm(-1). Here, w...
متن کاملExperiences in Pattern Recognition for Machine Olfaction
Pattern recognition is essential for translating complex olfactory sensor responses into simple outputs that are relevant to users. Many approaches to pattern recognition have been applied in this field, including multivariate statistics (e.g. discriminant analysis), artificial neural networks (ANNs) and support vector machines (SVMs). Reviewing our experience of using these techniques with man...
متن کاملThe molecular logic of olfaction in Drosophila.
Drosophila fruit flies display robust olfactory-driven behaviors with an olfactory system far simpler than that of vertebrates. Endowed with 1300 olfactory receptor neurons, these insects are able to recognize and discriminate between a large number of distinct odorants. Candidate odorant receptor molecules were identified by complimentary approaches of differential cloning and genome analysis....
متن کاملBiochemical studies of olfaction: role of cilia in odorant recognition.
Chemoreception in vertebrates is beginning to be understood. Numerous anatomical, behavioral, and physiological studies are now available. Current research efforts are examining the molecular basis of chemoreception. Rainbow trout (Salmo gairdneri) have a functional olfactory system and are a suitable vertebrate model for studying odorant interactions with receptors. Using a biochemical approac...
متن کاملMolecular vibration-sensing component in Drosophila melanogaster olfaction.
A common explanation of molecular recognition by the olfactory system posits that receptors recognize the structure or shape of the odorant molecule. We performed a rigorous test of shape recognition by replacing hydrogen with deuterium in odorants and asking whether Drosophila melanogaster can distinguish these identically shaped isotopes. We report that flies not only differentiate between is...
