(A) Measures of latency to reward by odor condition and sex (B) Normalized behavioral results collapsed across sex (C&D) Normalized behavioral results grouped by sex for animals in the MV (C) and PEA (D) conditions. Bolded dashed line indicates the unit circle of a one-fold increase, and dotted lines indicate subsequent increases (e.g., two-fold increase, three-fold increase, etc., compared to CB controls) in B, C, and D. Error bars show mean ± SEM. CB: n = 41 (19 males); MV: n = 38 (21 males); PEA: n = 40 (19 males). CB, clean bedding; MV, methyl valerate; PEA, phenylethylamine; M, male; F, female.
