Study reveals how olfactory neurons adapt to the surrounding environment.
Anosmia, the loss of the sense of smell which is a common symptom of COVID-19, may be a secondary consequence of immune system inflammation rather than a direct action of the virus.
Centrifugal fibers which carry impulses from parts of the central nervous system to early sensory regions of the brain play a critical role in olfactory processing.
Even mild COVID-19 infection can lead to cognitive alterations and brain shrinkage, researchers report. The findings could help explain the brain changes that contribute to long-COVID.
Infection with the SARS_CoV-2 virus causes dials down the action of olfactory receptors, resulting in smell loss associated with COVID-19.
Neurons in the primary olfactory cortex play a role in encoding spatial maps, a new study reports.
A majority of Parkinson's patients report a diminished sense of smell, which starts to occur a number of years before the onset of other symptoms. Researchers are exploring whether scent-processing neurons which connect the nose to the brain may play a role in the development of Parkinson's disease.
A new machine-learning algorithm is able to teach itself to smell within a few minutes of training. As it learns, the system builds an artificial network that mimics the brain's olfactory system.
Following injury or damage, insulin plays a key role in the maturation and regeneration of immature olfactory sensory neurons.
Regions of the olfactory system in mice with higher amyloid beta expression exhibited lower activation of olfactory sensory neurons and decreased odor detection.
Trained scent detection dogs are able to detect organic compounds associated with COVID-19 in patients. Researchers report the dogs are better at detecting coronavirus infection than standard tests.
Study finds olfaction plays a significant role in the motivation to exercise. Mice who were "high runners" developed genetic differences in their olfactory systems that caused them to perceive smells differently than more sedentary mice.
