MR Imaging–Based Evaluations of Olfactory Bulb Atrophy in …
WEBMar 1, 2018 · Olfactory bulb atrophy and neuropathy were evaluated on MR images by 2 head and neck radiologists. RESULTS: The etiology of olfactory loss was chronic rhinosinusitis with/without nasal polyps in 15 (44.1%) patients, respiratory viral infection in 7 (20.6%), trauma in 2 (5.9%), and idiopathic in 10 (29.4%) patients.
The Shape of the Olfactory Bulb Predicts Olfactory Function
WEBJan 18, 2022 · The olfactory bulb (OB) plays a key role in the processing of olfactory information. A large body of research has shown that OB volumes correlate with olfactory function, which provides diagnostic and prognostic information in olfactory dysfunction.
Non-invasive recording from the human olfactory bulb - Nature

Olfacotry bulb: Anatomy, function and parts | Kenhub
WEBOct 30, 2023 · The olfactory bulb is the main relay structure of the olfactory pathway. It contains the axons of the olfactory receptor cells which synapse with mitral cells in the olfactory bulb. The axons of these secondary neurons form the olfactory tract.
Functional anatomy and imaging of the olfactory pathway
WEBJan 7, 2021 · Experimental in vitro cadaveric imaging of the olfactory bulb using 9.4 T MR-microscopy has managed to identify six separate signal intensity layers representing the distinct cellular lamination pattern of the olfactory bulb .
Plasticity of the Human Olfactory System: The Olfactory Bulb
WEBSep 17, 2013 · Two major mechanisms have been proposed to explain the plasticity of the olfactory system. First, the continuous neurogenesis that occurs at the level of the olfactory neuroepithelium (purple). Second, the continuous neurogenesis from the subventricular zone of the lateral ventricle (SVZ).
Automatic Segmentation of the Olfactory Bulb - PMC
WEBAug 28, 2021 · Abstract. The olfactory bulb (OB) has an essential role in the human olfactory pathway. A change in olfactory function is associated with a change of OB volume. It has been shown to predict the prognosis of olfactory loss and its volume is a biomarker for various neurodegenerative diseases, such as Alzheimer’s disease.
