Genomic Mechanism Regulates Smell Receptor Selection

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, in the nose, and a […]

Olfactory Neuron Development Declines In Old Age

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 confetti reporters. They then analysed […]

Nose Breathing Improves Smell Memory Consolidation

Research into how breathing affects the brain has become an ever-more popular field in recent years and new methodologies have enabled more studies, many of which have concentrated on the memory. Researchers at Karolinska Institutet in Sweden now report that study participants who breathe through the nose consolidate their memories better. “Our study shows that […]
