Researchers discover as much as 30% of the larger array of human olfactory receptors differ between individuals.
Using fruit flies, researchers discover how the brain integrates multiple signals to identify unique smells.
Researchers use peanut butter as a new tool to diagnose early stage Alzheimer’s disease.
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 neuroimaging study reveals how anxiety or stress can link areas of the brain for emotion and olfactory processing, making neutral odors smell malodorous.
Researchers have mapped the activity of brain cells in the mushroom body of flies conditioned to have Pavlovian behavioral responses to different odors. The findings suggest the activity of as few as 25 neurons are required to be able to distinguish between different odors.
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.
Newborn mice use mom’s unique odor, not a pheromone, to begin breastfeeding.
Researchers recently localised and identified the most important types of nerve cells involved in forming positive and negative memories of a fruit fly. All four nerve cell types they discovered use dopamine to communicate with other nerve cells. Three of the nerve cell types assume various functions in mediating negative stimuli, while the fourth enables the fly to form positive memories.
