Mechanisms of scent-tracking in humans
&
Abstract
Whether mammalian scent-tracking is aided by inter-nostril comparisons is unknown. We assessed this in humans and found that (i) humans can scent-track, (ii) they improve with practice, (iii) the human nostrils sample spatially distinct regions separated by |[sim]|3.5 cm and, critically, (iv) scent-tracking is aided by inter-nostril comparisons.
