Assessment of Olfactory Memory in Olfactory Dysfunction
Perception, 2016To assess all clinically relevant components of olfactory perception, examinations for olfactory sensitivity, discrimination, and identification are performed. Besides the standard perceptual test battery, episodic olfactory memory might offer additional information about olfactory abilities relative to these standard clinical tests.

Olfactory Discrimination in the Rabbit Olfactory Glomerulus
Science, 1966Slow potentials evoked by odor stimulation were recorded from individual glomeruli in the olfactory bulb. Systematic analysis of responses to nine different, arbitrarily selected stimuli strongly suggests a certain amount of discrimination. This fact seems to reflect in the first synapse of the olfactory tract the type of discrimination that was ...

Modern humans live in real and digital environments dominated by sight and sound, but the vast majority of organisms on the planet rely on information received through air- or water-borne molecules to find food, avoid danger, and reproduce. Olfaction is at once both the primitive sensory modality and one of the hardest to understand, in large part due ...

Olfactory Function and Olfactory Bulb Volume in Patients with Postinfectious Olfactory Loss
The Laryngoscope, 2006AbstractObjective: The study aimed to investigate whether the degree of postinfectious olfactory loss is reflected in volume of the olfactory bulb (OB).Study Design: Retrospective study of 26 patients with postinfectious olfactory loss.Materials and Methods: Olfactory function was assessed with the “Sniffin Sticks” test kit, and the magnetic resonance ...

A case of olfactory neuroblastoma, type 1 (olfactory neurocytoma), in a 44-year-old man is described. The tumour grew extensively in the right nasal cavity with involvement of the maxillary sinus and ethmoidal region, but was radically removed at operation. The prognosis and treatment are discussed in the light of earlier literature.

Acta Neurochirurgica, 2007
We report a case of olfactory schwannoma with calcification. Intraoperative findings indicated that the tumour originated from the olfactory groove. Intraoperative findings of previous studies have not indicated a clear relationship between subfrontal schwannoma and the olfactory nerve, which seems strange, given the association between tumours and ...

Olfaction is an ancient sensory system allowing an organism to detect chemicals in its environment. The first step in odor transduction is mediated by binding odorants to olfactory receptors (ORs) which belong to the heptahelical G-protein-coupled receptor (GPCR) superfamily. Mammalian ORs are disposed in clusters on virtually all chromosomes. They are

This chapter discusses the anatomic basis of the olfactory sensation (smell) and symptoms and signs caused by its impairment. The primary neurons of the olfactory system are the bipolar cells located in the olfactory epithelium of the nasal mucous membrane (Figure 6-1).

Olfactory neuroblastoma is an uncommon malignant tumor arising from olfactory epithelium. Generally considered to be a tumor of slow growth, it varies in aggressiveness and may cause death by distant metastasis or local invasion. The pathologic diagnosis is difficult, and this tumor is often erroneously diagnosed.Nine previously unreported cases are ...

Olfactory neuroblastoma is a rare tumor. Nasal endoscopy typically identifies a soft mass arising from the olfactory cleft. Computer tomography and magnetic resonance imaging are mandatory for staging (in association with 18F-fluorodeoxyglucose positron emission tomography) in high-grade and/or high-stage tumors.
