TL;DR: The results show that COVID-19-associated chemosensory impairment is not limited to smell, but also affects taste and chemesthesis, and suggest that SARS-CoV-2 infection may disrupt sensory-neural mechanisms.
Journal ArticleDOI
Disruption of centrifugal inhibition to olfactory bulb granule cells impairs olfactory discrimination
TL;DR: Channelrhodopsin is used to stimulate GABAergic axons from the basal forebrain selectively and it is shown that this stimulation generates reliable inhibitory responses in GCs, indicating an important role of these inhibitory afferents in olfactory processing.
Journal ArticleDOI
Regulation of adult neurogenesis by behavior and age in the accessory olfactory bulb.
TL;DR: The results indicate that the physiological regulation of adult neurogenesis in the AOB by behaviors is both sex and age dependent and suggests an important role of newly born neurons in sex dependent behaviors mediated by the VNS.
Journal ArticleDOI
A follow-up on quantitative and qualitative olfactory dysfunction and other symptoms in patients recovering from COVID-19 smell loss.

TL;DR: While smell ability improves for many individuals who lost it during acute COVID-19, the prevalence of parosmia and phantosmia increases substantially over time, and healthcare providers worldwide need to be prepared to treat post CO VID-19 secondary effects on physical and mental health.
Journal ArticleDOI
Expression and Distribution of Facilitative Glucose (GLUTs) and Monocarboxylate/H+ (MCTs) Transporters in Rat Olfactory Epithelia
Alexia Nunez-Parra,Alexia Nunez-Parra,Christian Cortés-Campos,Juan Bacigalupo,Juan Bacigalupo,Maria de los Angeles Garcia,Francisco Nualart,Juan G. Reyes +7 more
TL;DR: The authors' observations suggest an energetic coupling between SCs and Bowman's gland cells, where glucose crossing the blood-mucosa barrier through GLUT1 is incorporated by these epithelial cells.
