Vascular and inflammatory problems during middle age, as well as some minor injuries, could be a biomarker for poor brain health in older age. However, brain aging may be delayed by maintaining a healthy diet, weight and level of physical activity as we age.
Age related neurodegeneration may be delayed by preventing oxidative damage in a few neuron types, researchers report.
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.
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.
ACE2 and TMPRSS2, two proteins required for SARS-CoV-2 entry, are produced in cells in the nasal cavity that contribute to odor detection. The findings may explain why people with coronavirus often describe the loss of the sense of smell as a symptom of the virus.
Olfactory imprinting in infant mice has a direct impact on their social behaviors as adults.
Researchers discover as much as 30% of the larger array of human olfactory receptors differ between individuals.
According to researchers, the ambient scent of foods can help to reduce cravings and satisfy the appetite.
A pheromone released by female zebrafish is sensed by the olfactory receptors of males, a new study reports.
