Neurons and circuits for odor processing in the piriform cortex [PDF]

, 2013
Increased understanding of the early stages of olfaction has lead to a renewed interest in the higher brain regions responsible for forming unified ‘odor images’ from the chemical components detected by the nose.

Early and Sustained Improvements in Sense of Smell With Tezepelumab Treatment in Patients With Chronic Rhinosinusitis With Nasal Polyps (WAYPOINT)

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Loss of smell is a principal symptom of chronic rhinosinusitis with nasal polyps (CRSwNP), affecting health‐related quality of life and posing a safety hazard. Methods WAYPOINT (NCT04851964), a phase 3, multicenter trial in adults with uncontrolled CRSwNP, randomized patients 1:1 to receive tezepelumab 210 mg or placebo ...

Conservation of Olfactory Avoidance in Drosophila Species and Identification of Repellents for Drosophila suzukii. [PDF]

, 2015
Flying insects use olfaction to navigate towards fruits in complex odor environments with remarkable accuracy. Some fruits change odor profiles substantially during ripening and related species can prefer different stages.

A neuroimaging study of pleasant and unpleasant olfactory perceptions of virgin olive oil [PDF]

, 2016
Functional magnetic resonance imaging (fMRI) has been used to collect information from neurons that receive direct input from olfactory bulbs when subjects smell virgin olive oil. The pleasant aroma of three extra virgin olive oils (var.

Appropriate Medical Therapy Primarily Modifies Type 2 and Severity Biomarkers in Chronic Rhinosinusitis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Appropriate medical therapy (AMT) is first‐line treatment for patients with chronic rhinosinusitis (CRS). We evaluated inflammatory structure, treatment‐induced changes, and biomarker‐outcome associations in AMT‐managed patients. Methods Fifty‐one CRS patients were evaluated before and after AMT which included a combination of oral ...

Olfactory Bulb Volume Reflects Olfactory Dysfunction and Network Organization: Insights From the Population‐Based Rhineland Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Olfactory dysfunction is common in aging and an early symptom of neurodegenerative diseases, but how structural (olfactory bulb [OB] volume) and functional (olfactory network [OFN] functional connectivity [FC]) brain features interact to shape odor identification ability remains unclear.

Key Odorants Regulate Food Attraction in Drosophila melanogaster

Frontiers in Behavioral Neuroscience, 2017
In insects, the search for food is highly dependent on olfactory sensory input. Here, we investigated whether a single key odorant within an odor blend or the complexity of the odor blend influences the attraction of Drosophila melanogaster to a food ...

Determining the Minimal Clinically Important Difference of the 40‐Item Smell Identification Test in People With Cystic Fibrosis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40‐item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF‐specific minimal clinically important difference (MCID) has not been ...

Floral and Bird Excreta Semiochemicals Attract Western Carpenter Ants

Frontiers in Ecology and Evolution, 2022
Ant colonies have vast and diverse nutritional needs but forager ants have limited mobility to meet these needs. Forager ants would accrue significant energy savings if they were able to sense and orient toward odor plumes of both carbohydrate and ...
