Characterizing functional pathways of the human olfactory system

eLife, 2019
The central processing pathways of the human olfactory system are not fully understood. The olfactory bulb projects directly to a number of cortical brain structures, but the distinct networks formed by projections from each of these structures to the ...

Effects of diazinon on olfactory epithelium and genes related to olfactory signal transduction in Caspian roach, Rutilus caspicus [PDF]

Caspian Journal of Environmental Sciences, 2021
Olfaction in fishes is biologically-essential chemoreceptors. It provokes important behaviors for the survival of fish such as feeding, reproduction, avoiding predator and intraspecific communication.

An Olfactory Receptor Pseudogene whose Function emerged in Humans [PDF]

, 2007
Human olfactory receptor, hOR17-210, is identified as a pseudogene in the human genome. Experimental data has shown however, that the gene product of cloned hOR17-210 cDNA was able to bind an odorant-binding protein and is narrowly tuned for excitation ...

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

, 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 ...

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

, 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.

Cortical Magnetic Resonance Imaging Findings in Patients With Posttraumatic Olfactory Dysfunction: Comparison According to the Interval Between Trauma and Evaluation [PDF]

Clinical and Experimental Otorhinolaryngology, 2014
ObjectivesPatients with smell loss after craniocerebral trauma are known to have some brain abnormalities, but there was no study to analyze the findings according to the time interval between injury and evaluation.

Studies on Clinical Features, Mechanisms, and Management of Olfactory Dysfunction Secondary to Chronic Rhinosinusitis

Frontiers in Allergy, 2022
Chronic rhinosinusitis (CRS) is one of the most common causes of inflammation of the olfactory system, warranting investigation of the link between chronic inflammation and the loss of olfactory function.

Oscillatory Sequences of Firing in the Locust Olfactory System: Mechanisms and Functional Significance [PDF]

, 1999
What neural codes does the brain use to represent and process sensory information? Stimulus-evoked oscillatory synchronization of neuronal activity has been observed in many systems, yet the possible functions of such rhythmic synchronization in neural ...

Enhanced odor discrimination and impaired olfactory memory by spatially controlled switch of AMPA receptors [PDF]

, 2005
Genetic perturbations of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptors (AMPARs) are widely used to dissect molecular mechanisms of sensory coding, learning, and memory.

Olfactory consciousness and gamma oscillation couplings across the olfactory bulb, olfactory cortex and orbitofrontal cortex

Frontiers in Psychology, 2013
The orbitofrontal cortex receives multi-modality sensory inputs, including olfactory input, and is thought to be involved in conscious perception of the olfactory image of objects.
