Olfaction: from odorant molecules to the olfactory cortex.
How do we smell? Our knowledge of how odor information from the environment is perceived has greatly advanced since the discovery of approximately 1,000 genes for odorant receptors in the mammalian genome. From the combination of molecular-genetic, electrophysiological, and optical imaging studies a better understanding of how we smell is emerging.
متن کاملFrom odor molecules to plume tracking: an interdisciplinary, multilevel approach to olfaction in stomatopods.
Like many marine crustaceans, mantis shrimp rely on their sense of smell to find food, mates, and habitat. In order for olfaction to function, odorant molecules in the surrounding fluid must gain access to the animal's chemosensors. Thus fluid motion is important for olfaction, both in terms of the large scale fluid movements (currents, waves, etc.) that advect the odorants to the vicinity of t...

متن کاملOlfaction.
The main and accessory olfactory systems have received considerable attention on the part of scientists and clinicians during the last decade, largely because of (a) quantum advances in understanding their genetically expressed receptor mechanisms, (b) evidence that their receptor cells undergo neurogenesis and both programmed and induced cell death, and (c) important technical and practical de...
متن کاملSpatial and temporal coding in an olfaction-inspired network model
Olfactory systems must solve a difficult combinatorial problem. Based on the architecture of the first synaptic relay of the olfactory system, we developed a model using Hodgkin-Huxley like equations to examine how local inhibition can contribute to developing a pattern of spiking activity that is related to features of synaptic input such as input strength. We also examine how changing synapti...
