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.
The sense of taste in female mosquitoes is specially tuned to detect at least four different substances in blood.
Women who experience unexplained repeated pregnancy loss (uRPL) process olfactory signals related to male body odor differently to other women. Those who experience uRPL are better able to identify the smell of their spouse.
Infection of non-neuronal supporting cells in the nose and forebrain may be responsible for the olfactory problems associated with COVID-19. Findings suggest olfactory sensory neurons are not vulnerable to coronavirus infection as they do not express ACE2.
Older adults with a higher ability to process sensations, including vision, olfaction, hearing, and touch, had half the risk of being diagnosed with cognitive decline than their peers who were less capable at sensory processing tasks.
Roughly 50% of patients hospitalized for COVID-19 experience neurological symptoms including headaches, dizziness, smell and taste disorders, and stroke, a new study reports. Coronavirus may affect the entire nervous system, including the brain, spinal cord, and muscles. Neurological symptoms of COVID-19 may appear before the fever and cough commonly associated with infection.
Researchers have developed a sniff test that can detect which patients in a vegetative state following a TBI will regain consciousness.
