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.
Women who experience unexplained repeated pregnancy loss (uRPL) process olfactory signals related to male body odor differently to other women. Those who experience uRPL are better able to identify the smell of their spouse.
Coronavirus can cause several significant neurological disorders, and the pandemic has been linked to a rise in people reporting mental health problems such as depression and anxiety. Researchers examine how COVID-19 affects brain and mental health and provides some techniques which can help to improve well-being during the pandemic.
Analyzing nasal discharge could be a new tool in diagnosing and monitoring the progression of Alzheimer's disease. Researchers found certain Alzheimer's related proteins can be detected in nasal discharge.
A simple smell test could help doctors to identify which patients in a vegetative state will recover. 100% of patients in a vegetative state who reacted to the sniff test went on to regain consciousness. 91% of those were still alive three years post-injury.
