Despite this simplicity, they are capable of detecting and appropriately responding to a Dallas, Texas 75235-9111 wide range of chemicals (Bargmann et al. Lucretius, one of the early Greek atomists, suggested have shown that chemoattraction to a number of mole-that all substances having odor gave o...

with OECs. These are the cells that ensheath the axons within the olfactory nerve and constitute the major glial component of the superficially located nerve fiber layer of the olfactory bulb. This property of the OEC to provide a permissive boundary between the PNS and CNS is The OEC, originally described by the Spanish histologist Blanes Viale at the end of the nineteenth century, shares prop...

متن کاملThe Sweet Smell of Success: Conclusive Evidence that Cyclic AMP Hydrolysis Does Not Trigger Fast Adaptation in Olfactory Receptor Cells
We are often taught that it is almost impossible to publish negative results. Yet, in this issue, Boccaccio, Lagostena, Hagen, and Menini (2006) have assembled a very impressive array of negative results that answer a critical question in olfactory transduction. In an elegant set of experiments, these authors have ruled out a suspected mechanism of fast olfactory adaptation and have, by default...
