Lobster olfactory genomics.
Lobsters have numerous adaptive specializations of the olfactory system that make them especially suitable model organisms for the study of olfaction. Recent work using genomics and physiological genomics to study the lobster olfactory organ extends the advantages of their use further. A subtracted cDNA library from the mature zone of the olfactory organ and 3 physiological genomics experiments...
متن کاملGenomics of olfactory receptors.
In many species, the sense of smell plays important roles in locating food, detecting predators, navigating, and communicating social information. The olfactory system has evolved complex repertoires of odor receptors (ORs) to fulfill these functions. Through computational data mining, OR repertoires of multiple species were identified, revealing a surprisingly large OR gene family in rodents a...
متن کاملNa+-gated nonselective cation channel from lobster olfactory projection neurons.
Na+-gated nonselective cation channel from lobster olfactory projection neurons. J. Neurophysiol. 80: 3387-3391, 1998. A nonselective cation channel specifically activated by intracellular Na+ was identified in cell-free patches taken from cultured lobster olfactory projection neurons. Na+ reversibly activates the channel in a concentration-dependent manner, with a "half-effect" Na+ concentrati...
متن کاملMechanisms of afterhyperpolarization in lobster olfactory receptor neurons.
In lobster olfactory receptor neurons (ORNs), depolarizing responses to odorants and current injection are accompanied by the development of an afterhyperpolarization (AHP) that likely contributes to spike-frequency adaptation and that persists for several seconds after termination of the response. A portion of the AHP can be blocked by extracellular application of 5 mM CsCl. At this concentrat...
متن کاملSpecificity of odorant-evoked inhibition in lobster olfactory receptor neurons.
Lobster olfactory receptor neurons, like those of many animals, use two modes of olfactory signaling, excitation and inhibition to code olfactory information. Inhibition appears to act through two distinct ionic mechanisms. Here we show that neither ionic mechanism is odor-specific, providing further support for the emerging understanding that there are no inhibitory odorants per se, but rather...
