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 ...

Olfactory Perception, Communication, and the Nose-to-Brain Pathway
Physiology and Behavior, 2004The present paper's aim is of to give an overview about the basic knowledge as well as actual topics of olfaction--with a special regard on behavior. We summarize different functions of the nose and the olfactory system in human physiology and psychology. We will first describe the functional anatomy of the olfactory system in man.

Hypothalamic Influences on the Electrical Activity of the Olfactory Pathway
Brain Research Bulletin, 1976By means of evoked potentials a direct efferent connection was found to run from the posterior hypothalmus and medial forebrain bundle to primary olfactory structures (olfactory bulb, olfactory tubercle and prepyriform cortex). The pathway from the hypothalmus to the olfactory bulb follows in the lateral olfactory tract at a conduction velocity 5-10 m ...

Uptake of Inorganic Mercury in the Olfactory Bulbs via Olfactory Pathways in Rats
Environmental Research, 1998Uptake and transport in the olfactory neurons may be an important means by which some heavy metals gain access to the brain. In the present study we explored whether inorganic mercury (203Hg2+) may be taken up in the CNS via the olfactory pathway.

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.

Olfactory pathways and the sense of smell
Neuroscience & Biobehavioral Reviews, 1992Rats were trained using operant conditioning to detect isoamyl acetate vapor generated by an olfactometer. They received lesions of olfactory pathways and were tested for retention of the odor detection task and trained on two-odor tasks. Deficits in odor detection and two-odor discrimination were related to the extent to which lesions disconnected the

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.

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.
