For many people, a sudden loss of smell is the first sign that something’s wrong. “One gentleman said he realized it with hand sanitizer. All of a sudden it was like water to him,” says Carol Yan, a rhinologist at the University of California, San Diego. The loss of smell,…Continue readingLoss Of Smell, Confusion, Strokes: Does Covid-19 Target The Nervous System?
Odor may alter the organization of relevant or fearful memories so that they are delayed in the de-contextualization process that occurs across time, suggests research from Boston University. Until now, the scent-memory connection has been something of an enigma. In fact, even the mechanisms that underlie memory formation in general…Continue readingOdor Changes How The Brain Processes Memories
Is it possible for an adult brain to make new nerve cells? Scientists have debated this question for decades, with many concluding that neuron-making (neurogenesis) stops after childhood, or around the age of 13. However, a research team recently rocked the debate again after finding a thriving neuron ‘nursery’ in…Continue readingThriving Neuron ‘Nursery’ Found In A Section Of Adult Human Nose Tissue
Effortless learning during sleep is a fantasy of many people. The supportive effect of smells on learning success when presented both during learning and sleep was first proven in an extensive sleep laboratory study. Researchers at the University of Freiburg Medical Center, the Freiburg Institute for Frontier Areas of Psychology…Continue readingThe Scent Of A Rose Improves Learning During Sleep
The large range of emotional and practical impacts caused by a loss of smell is elucidated in a new study from the University of East Anglia. It finds that almost every aspect of life is disrupted – from everyday concerns about personal hygiene to a loss of sexual intimacy and…Continue readingAnosmia – Is Loss Of Sense Of Smell Serious?
A genomic mechanism by which a finite number of genes can ultimately help distinguish a seemingly near-infinite number of scents has been identified by researchers from Columbia University. The human nose can distinguish one trillion different scents – an extraordinary feat that requires 10 million specialized nerve cells, or neurons,…Continue readingGenomic Mechanism Regulates Smell Receptor Selection
As mammals age, their sense of smell deteriorates. An interdisciplinary research team at Helmholtz Zentrum München and the University Medical Centre Mainz has investigated why this is the case. For their study, the researchers tracked the development of stem cells in the brains of mice using what are known as…Continue readingOlfactory Neuron Development Declines In Old Age
