Olfactory bulb surroundings can help to distinguish Parkinson’s disease from non-parkinsonian olfactory dysfunction

open access: yesNeuroImage: Clinical, 2020
Background: The olfactory bulb is one of the first regions of insult in Parkinson’s disease (PD), consistent with the early onset of olfactory dysfunction. Investigations of the olfactory bulb may, therefore, help early pre-motor diagnosis.

Nicotinic cholinergic regulation of olfactory bulb blood flow response in aged rats

open access: yesJournal 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

Neural connectivity predicts spreading of alpha-synuclein pathology in fibril-injected mouse models: Involvement of retrograde and anterograde axonal propagation. [PDF]

open access: yes, 2020
In Parkinson's disease, some of the first alpha-synuclein aggregates appear in the olfactory system and the dorsal motor nucleus of the vagus nerve before spreading to connected brain regions.

Cytological organization of the alpha component of the anterior olfactory nucleus and olfactory limbus

open access: yesFrontiers in Neuroanatomy, 2012
This study describes the microscopic organization of a wedge-shaped area at the intersection of the main and accessory olfactory bulbs, or olfactory limbus , and an additional component of the anterior olfactory nucleus or alpha accessory olfactory bulb ...

Olfactory neurogenesis and its role in fear memory modulation

open access: yesFrontiers 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 ...

Drug-induced Parkinson's disease modulates protein kinase A and Olfactory Marker Protein in the mouse olfactory bulb [PDF]

open access: yes, 2017
Background Olfaction is often affected in parkinsonian patients, but dopaminergic cells in the olfactory bulb are not affected by some Parkinson-inducing drugs.

Automatic Segmentation of the Olfactory Bulb [PDF]

open access: yesBrain Sciences, 2021
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.

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

open access: yes, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.

Lack of Pattern Separation in Sensory Inputs to the Olfactory Bulb during Perceptual Learning. [PDF]

open access: yes, 2017
Recent studies revealed changes in odor representations in the olfactory bulb during active olfactory learning (Chu et al., 2016; Yamada et al., 2017).

Plasticity in olfactory bulb circuits [PDF]

open access: yesCurrent Opinion in Neurobiology, 2020
Olfaction is crucial for animal survival and human well-being. The olfactory bulb is the obligatory input station for olfactory information. In contrast to the traditional view as a static relay station, recent evidence indicates that the olfactory bulb dynamically processes olfactory information in an experience-dependent and context-dependent manner.
