A morphometric study of the glomerular population in the olfactory bulb of the mouse has been carried out by using stereological methods. On the basis of the assumption that the glomerular population is a polydispersed system of spheres, glomerular profile distributions obtained from profile measurements were subjected to a mathematical unfolding procedure(More)
The present study explores the local variations of size and number of olfactory glomeruli induced by the exposure of young rats to long-term stimulation with a single odor. Three groups of 5 rats were used that were either: (1) stimulated with ethyl acetoacetate from birth to 1 month of age, (2) unilaterally deprived following early occlusion of one nare,(More)
Current models of sensory coding in the olfactory bulb are based on the notion of topographical specificity in the processing of stimuli. Part of this hypothesis comes from studies of patterns of radiolabelled 2-deoxyglucose uptake, and local morphometric variations of the mitral cell size observed following prolonged exposure to an odor. The present study(More)
63. Transmembrane-type guanylyl cyclases may also contribute to chemosensation. Guanylyl cyclase-D is expressed in a restricted subset of rodent OSNs that project to necklace glomeruli [H. The genome of C. elegans has 29 guanylyl cyclases, some of which are expressed in che-mosensory neurons (Their roles and ligands are not known. 64. I thank L. Buck and R.(More)
