Researchers find that SARS-CoV-2 infects sustentacular cells in the olfactory epithelium of COVID-19 patients
It is now widely known that COVID-19 is associated with the transient or long-term loss of olfaction (the sense of smell) but the mechanisms remain obscure. An unresolved question is whether the olfactory nerve can provide ...

New model show how the brain is organized to process odor information
Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the auditory system ...

Researchers map mouse olfactory glomeruli using state-of-the-art techniques
Detecting odors and differentiating between them is an essential ability that helps animals to survive and interact more effectively with their surrounding environment. In mammals, odors are known to be initially processed ...

Odor alternative: 'Olfactory necklace' detects scents in a way contrary to neurobiology dogma
Mammals have an exquisitely tuned sensory system that tells them whether they are smelling an orange or a rose. Like keys on a piano keyboard, each component of an odor blend strikes only one chord of olfactory neuron activation. ...

Signal and noise: Spike correlations in the olfactory system
(Medical Xpress)—The olfactory system is a particular favorite among the many who study neural coding. One reason for this is that presentation of a single odorant to an otherwise featureless smellscape, at least in theory, ...
