Fossil finding shed light on the changes in penguin brains that accompanied their transition to water, a new study reports.
Study reveals how the drosophila brain subconsciously processes salient information, such as odors, that require interpretation while asleep.
Biologists at UC San Diego have identified the molecular mechanisms triggered by starvation in fruit flies that enhance the nervous...
Inhibition of the OR5B21 olfactory receptor gene significantly decreased the metastasis of breast cancer cells to the brain, lungs, and bones, researchers report.
A new study sheds light on the ingenious mechanism that underlies the brain's ability to distinguish between different smells.
In one of the first successful attempts at genetically engineering mosquitoes, HHMI researchers have altered the way the insects respond to odors, including the smell of humans and the insect repellant DEET.
Experience and genetics give us all our unique sense of smell, a new study reports.
Researchers discover activity in brain regions involved in reward response from dopamine was higher in subjects injected with the hormone ghrelin, but only when responding to images associated with food smells. The study reports ghrelin controls the extent to which the brain associates reward with food odors.
Over 50% of patients with mild traumatic brain injury reported their sense of smell was diminished following concussion. The effect does not appear to be long term.
Researchers discover female mice can't sense the odor of male mice during the period of sexual inactivity during the reproductive cycle.
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.
