Latency to odor localization is increased in Ano2^−/− animals. (A) Examples of five Ano2^+/+ and Ano2^−/− animals tracking to the source of odorized air carrying a 1% dilution of peanut oil. Green and red asterisks mark the initial and final position of each animal. (B) Time latency for animals to locate the odor source (n = 8 Ano2^+/+ and 10 Ano2^−/− animals, p = 0.003, Wilcoxon rank-sum test). (C) Total distance traveled before finding the odor source across all animals (p = 0.002, Wilcoxon rank-sum test). (D) Initial distance from odor source (at odor onset) across all animals (p > 0.05, Wilcoxon rank-sum test). (E) Mean velocity of each animal prior to and following odor onset (p > 0.05, Wilcoxon rank-sum test).
