Olfaction

Olfaction.

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...

Evolution of avian olfaction

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...

Electric Times in Olfaction

Recent work established the spread of interglomerular excitation in the Drosophila antennal lobe. Two papers in this issue of Neuron, by Huang et al. and Yaksi and Wilson, show that cholinergic krasavietz local interneurons are a major substrate for this spread of excitation, predominantly via electrical coupling.

Mammalian Olfaction, Reproductive

Although for many animals olfactive perceptions must be the most important source of information about the state of their environment, we know relatively little about this chemoreceptive sensory system. The fact that our own sense of smell is comparatively rudimentary has certainly contributed to the relative lack of attention that olfactory behaviour and physiology have received. Our smelling ...
