Olfactory receptor antagonism between odorants.
The detection of thousands of volatile odorants is mediated by several hundreds of different G protein-coupled olfactory receptors (ORs). The main strategy in encoding odorant identities is a combinatorial receptor code scheme in that different odorants are recognized by different sets of ORs. Despite increasing information on agonist-OR combinations, little is known about the antagonism of ORs...
متن کاملEnvironmental Context—Dependent Memory
The impact on recall of reinstatement or change of the environment existing at the time of learning is reviewed. While strong and stable effects have been observed for recall, effects on recognition rarely occur because the word itself is a powerful cue (the outshining hypothesis). A classification of context effects is presented and the conditions where such effects are likely to be maximized ...
متن کاملHuman olfactory receptor responses to odorants
Although the human olfactory system is capable of discriminating a vast number of odors, we do not currently understand what chemical features are encoded by olfactory receptors. In large part this is due to a paucity of data in a search space covering the interactions of hundreds of receptors with billions of odorous molecules. Of the approximately 400 intact human odorant receptors, only 10% ...
متن کاملOlfactory receptor neuron profiling using sandalwood odorants.
The mammalian olfactory system can discriminate between volatile molecules with subtle differences in their molecular structures. Efforts in synthetic chemistry have delivered a myriad of smelling compounds of different qualities as well as many molecules with very similar olfactive properties. One important class of molecules in the fragrance industry are sandalwood odorants. Sandalwood oil an...
متن کاملContext-dependent olfactory learning in an insect.
We studied the capability of the cricket Gryllus bimaculatus to select one of a pair of odors and to avoid the other in one context and to do the opposite in another context. One group of crickets was trained to associate one of a pair of odors (conditioned stimulus, CS1) with water reward (appetitive unconditioned stimulus, US+) and another odor (CS2) with saline solution (aversive US, US-) un...
