Regions of the olfactory system in mice with higher amyloid beta expression exhibited lower activation of olfactory sensory neurons and decreased odor detection.
Mounting evidence suggests coronavirus affects the brain, in addition to the lungs. Researchers are examining the threat COVID-19 posses to long term brain health. They speculate maternal inflammation could lead to an increased risk of autism-like behaviors and neurodevelopment deficits in children born to mothers diagnosed with coronavirus. Other studies are exploring how the virus may spread in the nervous system via synaptic transmission.
Infection of non-neuronal supporting cells in the nose and forebrain may be responsible for the olfactory problems associated with COVID-19. Findings suggest olfactory sensory neurons are not vulnerable to coronavirus infection as they do not express ACE2.
Researchers describe what happens in the brain just prior to making a decision.
The anterior lateral motor cortex appears to play a significant role in context-based decision making.
Study reveals at least six types of mammals distinguish odors in similar ways, using neural networks that are evolutionarily preserved across species.
Researchers reveal neurons in the brains of fruit flies which specifically respond to food odors.The findings could help scientists better understand why obese people choose to eat certain foods.
A new study reveals the piriform cortex is able to archive long term memory, but requires instruction from the orbiotfrontal cortex to indicate the event is to be stored as a long-term memory.
The olfactory system works in combination with the brain's reward and aversion systems in both learning and memory formation.
Researchers explore how certain scents often elicit specific emotions and memories in people, and how marking companies are manipulating the link for branding.
The lateral horn has been identified as the processing center for behaviorally relevant odor information, a new study reports.
A new study reveals the emotional expression on other people's faces can influence whether we perceive an odor in a positive or negative light.
