Olfactory Optogenetics: Light Illuminates the Chemical Sensing Mechanisms of Biological Olfactory Systems

open access: yesBiosensors, 2021
The mammalian olfactory system has an amazing ability to distinguish thousands of odorant molecules at the trace level. Scientists have made great achievements on revealing the olfactory sensing mechanisms in decades; even though many issues need ...

An Artificial Olfactory System Based on a Chemi‐Memristive Device

open access: yesAdvances in Materials, 2023
Technologies based on the fusion of gas sensors and neuromorphic computing to mimic the olfactory system have immense potential. However, the implementation of neuromorphic olfactory systems remains in a state of infancy because conventional gas sensors ...

SARS-CoV-2 infection in the mouse olfactory system

open access: yesCell Discovery, 2021
SARS-CoV-2 infection causes a wide spectrum of clinical manifestations in humans, and olfactory dysfunction is one of the most predictive and common symptoms in COVID-19 patients.

Evolving the olfactory system with machine learning

open access: yesNeuron, 2021
The convergent evolution of the fly and mouse olfactory system led us to ask whether the anatomic connectivity and functional logic of olfactory circuits would evolve in artificial neural networks trained to perform olfactory tasks.

Non-neuronal expression of SARS-CoV-2 entry genes in the olfactory system suggests mechanisms underlying COVID-19-associated anosmia

open access: yesScience Advances, 2020
: Altered olfactory function is a common symptom of COVID-19, but its etiology is unknown. A key question is whether SARS-CoV-2 (CoV-2) – the causal agent in COVID-19 – affects olfaction directly, by infecting olfactory sensory neurons or their targets ...

A dopamine-gated learning circuit underpins reproductive state-dependent odor preference in Drosophila females

open access: yeseLife, 2022
Motherhood induces a drastic, sometimes long-lasting, change in internal state and behavior in many female animals. How a change in reproductive state or the discrete event of mating modulates specific female behaviors is still incompletely understood ...

The human olfactory system in two proteinopathies: Alzheimer’s and Parkinson’s diseases

open access: yesTranslational Neurodegeneration, 2020
Alzheimer’s and Parkinson’s diseases are the most prevalent neurodegenerative disorders. Their etiologies are idiopathic, and treatments are symptomatic and orientated towards cognitive or motor deficits.

Single-cell transcriptomes of developing and adult olfactory receptor neurons in Drosophila

open access: yeseLife, 2021
Recognition of environmental cues is essential for the survival of all organisms. Transcriptional changes occur to enable the generation and function of the neural circuits underlying sensory perception.

The Olfactory Bulb in Companion Animals—Anatomy, Physiology, and Clinical Importance

open access: yesBrain Sciences, 2023
The Olfactory Bulb is a component of the Olfactory System, in which it plays an essential role as an interface between the peripheral components and the cerebral cortex responsible for olfactory interpretation and discrimination.

Environmental Engineering Applications of Electronic Nose Systems Based on MOX Gas Sensors

open access: yesSensors, 2023
Nowadays, the electronic nose (e-nose) has gained a huge amount of attention due to its ability to detect and differentiate mixtures of various gases and odors using a limited number of sensors.
