The biological olfactory system is the sensory system responsible for the detection of the
chemical composition of the environment. Several attempts to mimic biological olfactory …

Detection and discrimination of odorants by the olfactory system plays a pivotal role in
animal survival. Olfactory-based behaviors must be adapted to an ever-changing …

Odor landscapes contain complex blends of molecules that each activate unique,
overlapping populations of olfactory sensory neurons (OSNs). Despite the presence of …

Persistent olfactory dysfunction (OD) is one of the most complaining and worrying
complications of long COVID-19 because of the potential long-term neurological …

Extant anuran amphibians originate from an evolutionary intersection eventually leading to
fully terrestrial tetrapods. In many ways, they have to deal with exposure to both terrestrial …

Humans have 396 unique, intact olfactory receptors (ORs), G-protein coupled receptors
(GPCRs) containing receptor-specific binding sites; other mammals have more. Activation of …

Although neglected by science for a long time, the olfactory sense is now the focus of a
panoply of studies that bring new insights and raises interesting questions regarding its …

Olfactory behavior is important for animal survival, and olfactory dysfunction is a common
feature of several diseases. Despite the identification of neural circuits and circulating …

The peptide hormones ghrelin and leptin play major roles in the regulation of appetite and
food intake. However, the precise effects of these hormones on sensory processing remain a …

Sex steroid hormones influence olfactory-mediated social behaviors, and it is generally
hypothesized that these effects result from circulating hormones and/or neurosteroids …
