Figure 4.

Behavioural differences in Trpa1 wild-type (WT) and knockout (KO) mice triggered by the fox odour, 2-MT. Remarkable differences were established in the duration and frequency of sniffing the odour holder (a,b) and freezing behaviour (c,d) between the two groups. The Gantt diagram presents the individual animals (e,f). n = 12 in both (WT and KO) groups, the symbol # shows a significant difference between the two genotypes, in cases with ### p < 0.001, and #### p < 0.0001. Blank triangles represent individual values while dark spots show outliers (characterized by a higher or lower value than mean ± 2 standard deviation (SD)).
