BMC Neuroscience, 2014 BackgroundThe main olfactory epithelium (MOE) in mammals is a specialized organ to detect odorous molecules in the external environment. The MOE consists of four types of cells: olfactory sensory neurons, supporting cells, basal cells, and microvillous ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT The addition of GPR120 agonists to vegetable oil or a fat‐containing food system enhances the fatty orosensation, an oily mouth‐coating sensed 5–10 s after tasting, in humans, although they have no fatty orosensation by themselves. To elucidate the role of GPR120 in the fatty orosensation in humans, the effects of GPR120 agonists and an ...

Disparity of turbinal bones in placental mammals
The Anatomical Record, EarlyView.Abstract Turbinals are key bony elements of the mammalian nasal cavity, involved in heat and moisture conservation as well as olfaction. While turbinals are well known in some groups, their diversity is poorly understood at the scale of placental mammals, which span 21 orders.

PLoS ONE, 2012 Neurogenesis continues in the adult brain and in the adult olfactory epithelium. The cytokine, leukaemia inhibitory factor and nitric oxide are both known to stimulate neuronal progenitor cell proliferation in the olfactory epithelium after injury.

Anosmia in COVID-19: Underlying Mechanisms and Assessment of an Olfactory Route to Brain Infection
The Neuroscientist, 2020 In recent months it has emerged that the novel coronavirus—responsible for the COVID-19 pandemic—causes reduction of smell and taste in a large fraction of patients.

, 2020 We perceive smells as perduring complex entities within a distal array that might be conceived of as smellscapes. However, the philosophical orthodoxy of Odor Theories has been to deny that smells are perceived as having a distal location.

Activity-Dependent Modulation of Odorant Receptor Gene Expression in the Mouse Olfactory Epithelium
PLoS ONE, 2013 Activity plays critical roles in development and maintenance of the olfactory system, which undergoes considerable neurogenesis throughout life. In the mouse olfactory epithelium, each olfactory sensory neuron (OSN) stably expresses a single odorant ...

The Anatomical Record, EarlyView.Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Alzheimer’s Disease: What Can We Learn From the Peripheral Olfactory System?
Frontiers in Neuroscience, 2020 The sense of smell has been shown to deteriorate in patients with some neurodegenerative disorders. In Parkinson’s disease (PD) and Alzheimer’s disease (AD), decreased ability to smell is associated with early disease stages.
