Smell Receptor Map Discovery in Mice

Scientists, led by Sandeep Robert Datta at Harvard Medical School, have created the first detailed map of how smell receptors are organized in the nose of Mouse. This discovery challenges the long-held belief that olfactory receptor expression was largely random, revealing instead a highly organized system of horizontal stripes based on receptor type. The research, published in Cell (journal), also established that this receptor map in the nose aligns with smell maps in the olfactory bulb of the brain, providing crucial insights into how olfactory information is processed. This foundational understanding is expected to pave the way for developing new therapies, such as stem cell treatments or brain-computer interfaces, to restore the sense of smell in humans, which has profound implications for health and psychological well-being. Funding for the research was provided by the United States — National Institutes of Health and the United States — National Science Foundation. A separate study by Catherine Dulac's lab at Harvard University also published consistent findings.
