Design and Validation of a Portable Machine Learning-Based Electronic Nose

Sensors, 2021
Volatile organic compounds (VOCs) are chemicals emitted by various groups, such as foods, bacteria, and plants. While there are specific pathways and biological features significantly related to such VOCs, detection of these is achieved mostly by human ...

Objective Olfactory Findings in Hospitalized Severe COVID-19 Patients

Pathogens, 2020
Objective: We investigate the prevalence of the self-reported and objective sudden loss of smell (SLS) in patients with severe coronavirus disease 2019 (COVID-19). Methods: Severe COVID-19 patients with self-reported SLS were recruited at hospitalization

Brain responses to odor mixtures with sub-threshold components

Frontiers in Psychology, 2013
Although most odorants we encounter in daily life are mixtures of several chemical substances, we still lack significant information on how we perceive and how the brain processes mixtures of odorants.

Characterizing neural coding performance for populations of sensory neurons: comparing a weighted spike distance metrics to other analytical methods

Frontiers in Neuroscience, 2023
The identity of sensory stimuli is encoded in the spatio-temporal patterns of responses of the encoding neural population. For stimuli to be discriminated reliably, differences in population responses must be accurately decoded by downstream networks ...

Using multisensory virtual reality nature immersion as a therapeutic modality for improving HRV and cognitive functions in post-traumatic stress disorder: a pilot-study

Frontiers in Virtual Reality, 2023
Introduction: Immersive virtual reality (VR) applications are burgeoning within healthcare as they promote high levels of engagement. Notwithstanding, existing solutions only stimulate two of our five senses (audio and visual), thus may not be optimal in

Anosmia-hyposmia and dysgeusia in COVID-19 may be due to SARS-CoV-2 protein mimicry of olfactory receptors [PDF]

Rhinology Online, 2020
Background: Anosmia-hyposmia and dysgeusia are common symptoms of mild-to-moderate COVID-19 cases. They are usually, but not always, reversible and the cause is unknown.

Axon tension regulates fasciculation/defasciculation through the control of axon shaft zippering

eLife, 2017
While axon fasciculation plays a key role in the development of neural networks, very little is known about its dynamics and the underlying biophysical mechanisms.

Olfactory neurogenesis plays different parts at successive stages of life, implications for mental health

Frontiers in Neural Circuits
The olfactory bulb is a unique site of continuous neurogenesis, primarily generating inhibitory interneurons, a process that begins at birth and extends through infancy and adulthood.

Functional Studies of Sex Pheromone Receptors in Asian Corn Borer Ostrinia furnacalis

Frontiers in Physiology, 2018
Lepidopteran insects use sex pheromones for sexual communication. Pheromone receptors expressed on peripheral olfactory receptor neurons (ORNs) are critical part to detect the sex pheromones. In genus Ostrinia, several pheromone receptors were functional
