Elderly humans can be identified by their unique body odor: research
New findings from the Monell Center reveal that humans can identify the age of other humans based on differences in body odor. Much of this ability is based on the capacity to identify odors of elderly individuals, and contrary ...

Gene mapping reveals architecture that controls expression of genes responsible for our sense of smell
Within the nasal cavity, millions of sensory neurons in a postage-stamp-sized patch of tissue called the olfactory epithelium control our sense of smell. Thanks to the exquisitely controlled expression of ...

New model show how the brain is organized to process odor information
Just like a road atlas faithfully maps real-word locations, our brain maps many aspects of our physical world: Sensory inputs from our fingers are mapped next to each other in the somatosensory cortex; the ...
