The year 2020 became the year of the outbreak of coronavirus, SARS-CoV-2, which
escalated into a worldwide pandemic and continued into 2021. One of the unique symptoms …

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 …

Volatile chemicals in the environment provide ethologically important information to many
animals. However, how animals learn to use this information is only beginning to be …

Pacific salmon are well known for their homing migrations; juvenile salmon learn odors
associated with their natal streams prior to seaward migration, and then use these retained …

Understanding how genes and experience work in concert to generate phenotypic variability
will provide a better understanding of individuality. Here, we considered this in the main …

Mammals typically have hundreds of distinct olfactory sensory neuron subtypes, each
defined by expression of a specific odorant receptor gene, which undergo neurogenesis …

In mammals, olfactory sensory neurons (OSNs) are born throughout life, presumably solely
to replace neurons lost via turnover or injury. This assumption follows from the hypothesis …

The main olfactory epithelium initiates the process of odor encoding. Recent studies have
demonstrated intergenerationally inherited changes in the olfactory system in response to …

A reduction in adult neurogenesis is associated with behavioral abnormalities in patients
with Alzheimer's disease. Consequently, enhancing adult neurogenesis represents a …

Olfactory disorders may be temporary or permanent and can have various causes. Currently,
many COVID-19 patients report a reduced or complete loss of olfactory function. A wide …
