That's all very well, but I am still not convinced at all that what works for a mouse will work just as well for humans. Oh, well, at least this is serious research, and I don't smell a rat! Hats off to people who can work with mouse urine, though....

Researchers Show How Brain Decodes Complex Smells
Duke University Medical Center researchers have discovered how the
brain creates a scent symphony from signals sent by the nose.
Extracellular recordings from a single male-urine-specific neuron in
the main olfactory bulb of a mouse. The responses of the neuron to
repeated presentations of volatiles from male urine (top panel) or
female urine (bottom panel) are shown. The histograms show the summed
responses. This neuron fired robustly in response to male urine
volatiles (the horizontal lines represent individual stimulus
presentations; the tick marks denote firing of the neuron) and showed
almost no response to female urine volatiles. (Image courtesy of Duke
