A study of hungry mice sheds new light on the neurobiology of olfaction and food attraction. Researchers identified a pathway that promotes attraction to food odors over other olfactory cues. Read More
Olfactory imprinting in infant mice has a direct impact on their social behaviors as adults. Read More
Study reveals how innate valence is encoded in the nervous system of mice. Read More
Researchers discovered unique connectivity between the hippocampus and olfactory areas in the brain, a finding which explains why specific odors can trigger powerful memories. The study also reports a loss of sense of smell is associated with depression and a poorer quality of life. Read More
Regions of the olfactory system in mice with higher amyloid beta expression exhibited lower activation of olfactory sensory neurons and decreased odor detection. Read More
51% of COVID-19 patients report they experienced the loss of smell and taste up to five months after infection. On average, once their senses were restored, people reported a loss in sensitivity to smell and taste. Read More
Both the orthonasal and retronasal routes, in addition to our taste buds, shape our taste perception of foods. Read More
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. Read More
Our sense of smell and hearing could have a significant impact on self-image and body perception. Read More
The smell of a cooperative rat is enough to trigger altruistic responses in other rodents. Read More
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. Read More
Witnessing bad behaviors triggers similar neural responses to those triggered by noxious smells. The study also pinpoints a biomarker in the brain for disgust. Read More
