Olfactory Bulb MRI and Paranasal Sinus CT Findings in Persistent COVID-19 Anosmia
Academic Radiology, 2020 Background and purpose There is limited literature consisting of case reports or series on olfactory bulb imaging in COVID-19 olfactory dysfunction. An imaging study with objective clinical correlation is needed in COVID-19 anosmia in order to better ...

Grafting the Olfactory Epithelium to the Olfactory Bulb [PDF]
American Journal of Rhinology & Allergy, 2009 Background Impaired olfactory function leads to a decrease in the quality of life for many patients. Surgical treatment options are limited, especially for those suffering from hyposmia or anosmia after posttraumatic injury to the olfactory nerves.

Assessment of olfactory nerve by SPECT-MRI image with nasal thallium-201 administration in patients with olfactory impairments in comparison to healthy volunteers. [PDF]
PLoS ONE, 2013 PURPOSE: The aim of this study was to assess whether migration of thallium-201 ((201)Tl) to the olfactory bulb were reduced in patients with olfactory impairments in comparison to healthy volunteers after nasal administration of (201)Tl.

COVID-19-induced anosmia associated with olfactory bulb atrophy
Neuroradiology, 2020 As the global COVID-19 pandemic evolves, our knowledge of the respiratory and non-respiratory symptoms continues to grow. One such symptom, anosmia, may be a neurologic marker of coronavirus infection and the initial presentation of infected patients ...

Connectivity and dynamics in the olfactory bulb [PDF]
PLOS Computational Biology, 2021 Dendrodendritic interactions between excitatory mitral cells and inhibitory granule cells in the olfactory bulb create a dense interaction network, reorganizing sensory representations of odors and, consequently, perception. Large-scale computational models are needed for revealing how the collective behavior of this network emerges from its global ...

Nicotinic cholinergic regulation of olfactory bulb blood flow response in aged rats
Journal of Physiological Sciences, 2023 In our previous research, we had demonstrated the crucial role of neuronal nicotinic acetylcholine receptors (nAChRs) in potentiation of the olfactory bulb blood flow response to olfactory stimulation in adult rats. The present study examined the effects

Olfactory neurogenesis and its role in fear memory modulation
Frontiers in Behavioral Neuroscience, 2023 Olfaction is a critical sense that allows animals to navigate and understand their environment. In mammals, the critical brain structure to receive and process olfactory information is the olfactory bulb, a structure characterized by a laminated pattern ...
