Female mice exposed to PBDEs, a type of flame-retardant found on everyday household items, pass on the chemicals to their developing offspring. In female offspring, this can cause alterations in social memories and behaviors which are reminiscent of human compulsive behaviors associated with autism.
A new study reports that being pleasantly surprised or disappointed with a certain food product can change a person's mood.
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...
A gene commonly associated with the sense of touch may also play an important role in the sense of smell, researchers report.
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.
