In the olfactory system, tufted cells are better at recognizing smells than mitral cells. Tufted cells are one of two parallel neural circuit loops that help the brain process different odor features. The findings shed light on how the brain takes in sensory information that influences behavior and emotion.
The neural circuitry that connects olfactory information about another mouse's sex to decision-making in the brain determines the behavioral outcome as to whether aggression or affection is expressed.
Using ultrasound, researchers captured the facial expressions of developing fetuses in response to the taste of foods their mothers were eating. When exposed to carrots, the fetuses displayed "laughter-face" expressions, and "crying-face" expressions when exposed to kale. The findings shed new light on the development of human taste and olfactory receptors.
Researchers found a significant link between olfaction and visual sensory processing, reporting specific smells influence the identification of facial emotions, and facial expressions influence the emotional response to smell.
The smell of fresh cut grass or blooming flowers appears to have a positive effect on a person's overall well-being, a new study reveals. Researchers say the smells of nature can help boost psychological well-being.
Study questions whether smell loss associated with COVID-19 infection may increase the risk of developing dementia later in life.
Smell loss in older individuals not only can predict cognitive decline, but it can also foretell structural changes in brain structures linked to Alzheimer's disease, a new study reports.
Medications that block serotonin and dopamine enable the life extension effect of the FMO protein in C. elegans, even in the presence of the smell of food.
A new robotic system can identify volatile organic compounds associated with diseases by analyzing bodily emissions.
Olfactory dysfunction can have both physical and social consequences, in addition to influencing food intake and weight. Researchers say foods that stimulate other chemical senses when consumed, such as chili or menthol, can improve life quality for those with olfactory dysfunction.
People have a tendency to form friendships with others who have a similar natural body odor, a new study reports. Using an electronic eNose to "smell" body odor, researchers were able to predict the quality of social interaction between strangers.
