Neuroethology utilizes a wide range of multidisciplinary approaches to decipher neural
correlates of natural behaviors associated with an animal's ecological niche. By placing …

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 …

INTRODUCTION The mammalian nose is arguably the best chemical sensor on the planet,
able to detect and discriminate among a large and diverse repertoire of mostly small …

Essential oils have been used in multiple ways, ie, inhaling, topically applying on the skin,
and drinking. Thus, there are three major routes of intake or application involved: the …

How the olfactory system detects and distinguishes odorants with diverse physicochemical
properties and molecular configurations remains poorly understood. Vertebrate animals …

Paradoxically, although humans have a superb sense of smell, they don't trust their nose.
Furthermore, although human odorant detection thresholds are very low, only unusually …

Mammals can perceive and discriminate myriad volatile chemicals as having a distinct odor.
Odorants are initially detected by odorant receptors (ORs) on olfactory sensory neurons …

The sense of smell collects vital information about the environment by detecting a multitude
of chemical odorants. Breadth and sensitivity are provided by a huge number of …

Evolution sculpts the olfactory nervous system in response to the unique sensory challenges
facing each species. In vertebrates, dramatic and diverse adaptations to the chemical …

The mammalian odorant receptor (OR) repertoire is an attractive model to study evolution,
because ORs have been subjected to rapid evolution between species, presumably caused …
