Figure 6: Example of behaviour with crossed and uncrossed nostril tubes.
From: Stereo and serial sniffing guide navigation to an odour source in a mammal
(a,b) In the course of 10 trials for each condition, the distance travelled to reach the food (or a position 1 cm past the food as indicated by the dashed line) was significantly greater for the crossed nostril condition (two-tailed t-test, P=0.03 for a and P<0.001 for b). Time measurements are not shown as they were substantially equivalent to distance. The position tracked was the midpoint between the openings of the nostril tubes. The dark square represents 1 cm2. Panel a corresponds to animal no. 19 and panel b corresponds to animal no.20. (see Supplementary Movie 7). Bars are s.e. of the mean.
