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...
متن کاملAssessment of olfaction in multiple sclerosis: evidence of dysfunction by olfactory evoked response and identification tests.
OBJECTIVE To resolve whether the olfactory pathways are affected in multiple sclerosis. METHODS Olfaction was assessed by: (1) The University of Pennsylvania smell identification test (UPSIT, which uses microencapsulated odours that are released when scratched with a pencil) in 72 patients with multiple sclerosis and 96 controls, (2) olfactory evoked potentials (OEP) to 20 ppm H2S by volume, ...
متن کاملEvolution 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...
متن کاملElectric 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.
