Olfactory Marker Protein in the Human Olfactory Pathway
Archives of Otolaryngology - Head and Neck Surgery, 1985The presence of olfactory marker protein (OMP) in the olfactory tissue of rats, gerbils, and humans was demonstrated with goat antiserum to rat OMP. In control studies on rat neural tissue, OMP was found to be located in the olfactory receptor cells, nerves, and bulbs. Likewise, staining of OMP was found in the olfactory tissues of gerbils.

Neurotrophic factors in the primary olfactory pathway
Progress in Neurobiology, 2000The number of identified growth factors continues to increase rapidly with many being implicated in the development of the nervous system, although for most of them the autocrine and paracrine pathways of cellular regulation still remain to be elucidated.

Carnosine in the Primary Olfactory Pathway
Science, 1974Carnosine (β-alanyl-L-histidine) is present in mouse olfactory bulbs and nasal olfactory epithelium at concentrations exceeding that previously reported for any brain region of any species. After peripheral deafferentation, carnosine concentrations in the olfactory bulbs decrease to less than 10 percent that of normal, while other amino compounds are ...

Brain, Behavior and Evolution, 2008
Recent evidence has revealed that some primary olfactory fibers bypass the olfactory bulb and terminate in tel- and/or diencephalic areas (extrabulbar olfactory pathway, EBOP). We investigated the projections of this system in different fishes by means of soybean agglutinin binding studies. In all species in which primary olfactory fibers were labelled,

Molecular Development of the Olfactory Nerve Pathway
Annals of the New York Academy of Sciences, 1998ABSTRACT: There are, at least, two major questions concerning the molecular development of the olfactory nerve pathway. First, what are the molecular cues responsible for guiding axons from the nasal cavity to the olfactory bulb? Second, what is the molecular basis of axon targeting to specific glomeruli once axons reach the olfactory bulb?

Changes in Peripheral Olfactory Pathways in Rheumatoid Arthritis
Journal of Computer Assisted Tomography, 2021Objectives We investigated olfactory bulb (OB) volumes and olfactory sulcus (OS) depths in patients with rheumatoid arthritis (RA). Methods In this retrospective study, cranial magnetic resonance images of 68 adult patients were included.

Anatomy of the Human Olfactory Bulb and Central Olfactory Pathways
1991The olfactory system subserves important functions, including the perception of flavor and smell. Although olfaction has traditionally received limited attention in both normal and pathological conditions in humans, this sensory system is now of considerable interest to neurobiologists and medical practitioners.This interest has been brought about, in ...

Electrophysiology of the olfactory pathway in the pigeon
Journal of Comparative Physiology ? A, 1980This work is part of an extensive study of anatomical, physiological, and behavioral characteristics of the olfactory system of birds. The present report deals primarily with the evoked potentials recorded from the olfactory bulb and several forebrain sites following electrical stimulation of one olfactory nerve.

Some olfactory pathways in the rabbit brain
Journal of Comparative Neurology, 1966AbstractThe degeneration pattern in the rabbit following transection of the olfactory bulb or peduncle at various levels was studied by the Laidlaw method of Nauta. Degenerating axons were observed in the crossing of the anterior limb of the anterior commissure and in the lateral olfactory tract following olfactory bulb lesions which did not damage the

Development of the Olfactory Pathways in Platypus and Echidna
Brain, Behavior and Evolution, 2011The two groups of living monotremes (platypus and echidnas) have remarkably different olfactory structures in the adult. The layers of the main olfactory bulb of the short-beaked echidna are extensively folded, whereas those of the platypus are not. Similarly, the surface area of the piriform cortex of the echidna is large and its lamination complex ...
