Olfaction scaffolds the developing human from neonate to adolescent and beyond

open access: yesPhilosophical Transactions of the Royal Society of London. Biological Sciences, 2020
The impact of the olfactory sense is regularly apparent across development. The fetus is bathed in amniotic fluid (AF) that conveys the mother's chemical ecology. Transnatal olfactory continuity between the odours of AF and milk assists in the transition

Assessing Olfaction Using Ultrasonic Vocalization Recordings in Mouse Pups with a Sono-olfactometer [PDF]

open access: yesBio-protocol , Bio-protocol LCC, 2019, 9 (4), 2019
Olfaction is the first sensory modality to develop during fetal life in mammals, and plays a key role in the various behaviors of neonates such as feeding and social interaction. Odorant cues (i.e., mother or predator scents) can trigger potentiation or inhibition of ultrasonic vocalizations (USV) emitted by pups following their isolation.

Poor human olfaction is a 19th-century myth

open access: yesScience, 2017
Humans have a good sense of smell In comparison to that of other animals, the human sense of smell is widely considered to be weak and underdeveloped. This is, however, an unproven hypothesis.

Olfaction-inspired MCs: Molecule Mixture Shift Keying and Cross-Reactive Receptor Arrays [PDF]

open access: yesarXiv, 2022
In this paper, we propose a novel concept for engineered molecular communication (MC) systems inspired by animal olfaction. We focus on a multi-user scenario where several transmitters wish to communicate with a central receiver. We assume that each transmitter employs a unique mixture of different types of signaling molecules to represent its message ...

Inverse resource allocation between vision and olfaction across the genus Drosophila

open access: yesNature Communications, 2019
Divergent populations across different environments are exposed to critical sensory information related to locating a host or mate, as well as avoiding predators and pathogens.

The role of SNMPs in insect olfaction

open access: yesCell and Tissue Research, 2020
The sense of smell enables insects to recognize olfactory signals crucial for survival and reproduction. In insects, odorant detection highly depends on the interplay of distinct proteins expressed by specialized olfactory sensory neurons (OSNs) and ...

Olfaction in dentistry [PDF]

open access: yesOral Diseases, 2010
Oral Diseases (2010) 16, 221–232Practitioners of oral medicine frequently encounter patients with complaints of taste disturbance. While some such complaints represent pathological processes specific to the gustatory system, per se, this is rarely the case.

Quantum Origins of Molecular Recognition and Olfaction in Drosophila [PDF]

open access: yes, 2012
The standard model for molecular recognition of an odorant is that receptor sites discriminate by molecular geometry as evidenced that two chiral molecules may smell very differently. However, recent studies of isotopically labeled olfactants indicate that there may be a molecular vibration-sensing component to olfactory reception, specifically in the ...

Relationship Between Poor Olfaction and Mortality Among Community-Dwelling Older Adults

open access: yesAnnals of Internal Medicine, 2019
The human sense of smell gradually decreases with age. Olfactory impairment or poor sense of smell affects up to 25% of U.S. older adults and, unlike hearing or vision impairment, often goes unrecognized (1, 2).

Feasibility of integrating canine olfaction with chemical and microbial profiling of urine to detect lethal prostate cancer

open access: yesbioRxiv, 2020
Prostate cancer is the second leading cause of cancer death in men in the developed world. A more sensitive and specific detection strategy for lethal prostate cancer beyond serum prostate specific antigen (PSA) population screening is urgently needed ...
