Evolution of Insect Olfaction
Neuroethology utilizes a wide range of multidisciplinary approaches to decipher neural correlates of natural behaviors associated with an animal's ecological niche. By placing emphasis on comparative analyses of adaptive and evolutionary trends across species, a neuroethological perspective is uniquely suited to uncovering general organizational and biological principles that shape the function...
متن کاملInsect Olfaction: Telling Food from Foe
The same sensory signal can be interpreted differently according to context. A new study in Drosophila uses cell-type-specific tools to identify neural circuits that integrate context during olfactory processing and surprisingly implicates memory-recall neurons.
متن کاملClinical studies of olfaction.
Disorders of the senses of taste and smell are not uncommon, occurring in over three million adults in the United States alone. Olfactory dysfunction occurs in about half of the population between the ages of 65 and 80 years and in about three-quarters of those 80 years of age and older (Figure 1). Although rarely appreciated, taste and smell disorders have significant consequences for the pati...
متن کاملSmelling the difference: controversial ideas in insect olfaction.
In animals, the sense of smell is often used as a powerful way to attract potential mates, to find food and to explore the environment. Different animals evolved different systems to detect volatile odorants, tuned to the specific needs of each species. Vertebrates and nematodes have been used extensively as models to study the mechanisms of olfaction: the molecular players are olfactory recept...
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....
