Sex-divergent effects on the NAD+-dependent deacetylase sirtuin signaling across the olfactory–entorhinal–amygdaloid axis in Alzheimer’s and Parkinson’s diseases

open access: yesBiology of Sex Differences, 2023
Highlights Quantitative proteomics is a useful approach to biochemically characterize the pathological neurodegeneration that occurs at the level of olfactory areas. Alteration in the olfactory tract proteostasis is more severe in AD than in PD.

Morphological features of changes in peripheral olfactory structures in SARS-COV-2 coronavirus infection

open access: yesPatologìâ, 2021
Coronavirus infection caused by the SARS-CoV-2 virus is an extremely important and urgent problem of modern medicine. It spreads quickly, has a high probability of a severe course and a large number of critical complications in patients from the risk ...

Analysis of spontaneous regeneration of olfactory structures with emphasis on myelination and re-innervation of cortical areas [PDF]

open access: yes, 2013
Regeneration of the lateral olfactory tract (LOT) occurs spontaneously after transection in developing rats. In neonatally LOT-transected rats, we observed a newly formed myelinated tract near the rhinal sulcus.

Prominent facilitation at beta and gamma frequency range revealed with physiological calcium concentration in adult mouse piriform cortex in vitro. [PDF]

open access: yesPLoS ONE, 2017
Neuronal activity is characterized by a diversity of oscillatory phenomena that are associated with multiple behavioral and cognitive processes, yet the functional consequences of these oscillations are not fully understood.

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

open access: yes, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Clinical, radiological, surgical, and pathological determinants of olfactory groove schwannoma

open access: yesIndian Journal of Neurosurgery, 2014
Background Olfactory groove schwannomas (OGS) are rare anterior cranial fossa base tumors with only 41 cases reported in literature. Olfactory ensheathing cell schwannoma (OECS) has similar clinico-radiological features as OGS, but a different cell of ...

Quantitative analysis of the olfactory system in pediatric epilepsy: a magnetic resonance imaging study

open access: yesDiagnostic and Interventional Radiology, 2023
PURPOSEOlfactory dysfunction is a well-known complication in epilepsy. Studies have demonstrated that olfactory bulb volume (OBV), olfactory tract length (OTL), and olfactory sulcus depth (OSD) can be reliably evaluated using magnetic resonance imaging ...

A case of olfactory neuroblastoma that presented with olfactory dysfunction after a COVID-19 diagnosis

open access: yesHeliyon, 2023
Background: Olfactory dysfunction is associated with conditions such as respiratory tract infections, trauma, sinonasal diseases, and neurodegenerative diseases.

Exploring olfactory sensory networks: Simulations and hardware emulation [PDF]

open access: yes, 2010
Olfactory stimuli are represented in a highdimensional space by neural networks of the olfactory system. A great deal of research in olfaction has focused on this representation within the first processing stage, the olfactory bulb (vertebrates) or ...

The mouse olfactory peduncle. 2.The anterior limb of the anterior commissure

open access: yesFrontiers in Neuroanatomy, 2013
The central core of the olfactory peduncle (the tissue connecting the olfactory bulb to the forebrain) includes a white matter tract that extends caudally to the anterior commissure.
