Humans rank among the species with the keenest sense of smell in the animal kingdom. https://link.springer.com/book/10.1007%2F978-3-662-57261-0 … Humans actually have THE keenest sense of smell - for the food in their mouth. https://plus.google.com/101046916407340625977/posts/844vhF48QoQ …pic.twitter.com/I1f0TOAbKO
Didn't know this: The former east German Intelligence agency, commonly known as the "Stasi" (as in "The Lives of Others"), made its mark in olfaction research. https://link.springer.com/book/10.1007%2F978-3-662-57261-0 …pic.twitter.com/5bvOapR5xo
humans probably worse at discriminating between odorants (fewer classes of odorant receptors)
(1) This experiment shows that humans share the same behavioral strategy when it comes to using odor cues in spatial navigation - not a discrimination performance study. (2) The number of odor receptors is not a sign of higher discriminatory power per se:https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0020146 …
yeah sorry, wasn't trying to claim this study related to discrimination just referring to another human-olfaction study
Ah, ok, my bad. Ambiguous medium, Twitter. Anyway, Shepherd's piece is pretty awesome, so I thought FYI!
This is really surprising. I was so sure that many animals had far better smell than humans. Of course, the comparison rests completely on which scents are tested. It seems the researcher has chosen scents based on their relevance to humans.
Also, we compare ourselves with dogs and cats who both have better smell, especially the former
I also had some idea that humans compensated for their relative deficiencies in terms of smell with superior vision and cognitive skills. Sort of an evolutionary trade-of: - many large mammals: fantastic smell - humans: fantastic sight+brains Maybe there is nothing to that.
There are many myths that have been debunked...https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.0020146 …
I once read that dogs can distinguish the smell of any human except for identical twins. Bears, (though hard to test) must have incredible olfactory abilities.
SA-PI-ENS! SA-PI-ENS!
I wonder how much this fidelity comes from sensitive receptors vs. focused processing. With attention I can smell stress, psychoactive compounds and arousal on people.
