Temporal coding of odor mixtures in an olfactory receptor neuron.
Most natural odors are mixtures and often elicit percepts distinct from those elicited by their constituents. This emergence of a unique odor quality has long been attributed to central processing. Here we show that sophisticated integration of olfactory information begins in olfactory receptor neurons (ORNs) in Drosophila. Odor mixtures are encoded in the temporal dynamics as well as in the ma...
متن کاملOlfactory Coding: Giant Inhibitory Neuron Governs Sparse Odor Codes
Electrophysiological investigations in locusts have revealed that the sparseness of odor representations, in the brain region expected to mediate olfactory learning, is shaped by a unique inhibitory neuron.
متن کاملMechanisms of olfactory receptor neuron specification in Drosophila
Detection of a broad range of chemosensory signals is necessary for the survival of multicellular organisms. Chemical signals are the main facilitators of foraging, escape, and social behaviors. To increase detection coverage, animal sensory systems have evolved to create a large number of neurons with highly specific functions. The olfactory system, much like the nervous system as a whole, is ...
متن کاملModulation of Olfactory Receptor Neuron Sensitivity by Hunger in Drosophila
Hunger drives animals to search for food, a behavior that is heavily dependent on the olfactory system. The neuronal mechanism by which hunger modulates the behavioral response towards food odor, however, is not well understood. In this study, using a single-fly behavioral assay and single-unit recording, we have demonstrated that starved flies exhibit enhanced attraction towards an attractive ...
متن کاملDisruption of olfactory receptor neuron patterning in Scutoid mutant Drosophila.
Olfactory neurons show an extreme diversity of cell types with each cell usually expressing one member from a large family of 60 Odorant receptor (Or) genes in Drosophila. Little is known about the developmental processes and transcription factors that generate this stereotyped pattern of cellular diversity. Here we investigate the molecular and cellular basis of defects in olfactory system fun...
