Scientists Develop First Smell Map: New Research Sheds Light on How Information Travels from Nose to Brain

Two teams of researchers looked beyond that conventional wisdom, and the results of their work, published in the latest issue of Cell, represent a major breakthrough in sensory biology and our understanding of how smell is perceived. They found that there is an orderly pattern of nasal receptors, and that order corresponds to the way the brain cells that receive olfactory signals are organized.
